This chemistry video tutorial provides a basic introduction into reaction mechanisms within a chemical kinetics setting. It explains how to write the rate law expression for a reaction mechanism. A reaction mechanism consist of a series of elementary steps or elementary reactions whose rate law can be written from its molecularity - that is from the coefficients of the balanced reaction. The rate of a reaction mechanism is completely dependent on the slow step or the rate-determining step. This video explains how to substitute an intermediate when writing rate law expressions. It contains plenty of examples and practice problems.

How To Identify The Intermediate & Catalyst In a Reaction Mechanism - Kinetics Chemistry
 
05:15
This chemistry video tutorial explains how to identify the intermediate and the catalyst in a reaction mechanism. It's important to understand that the intermediate and the catalyst do not show up in the overall reaction mechanism. The catalyst is present at the beginning and shows up at the end. It appears first on the left side and then reappears on the right side. The intermediate appears on the right side and then shows up on the left side later. The intermediate is produced first and then consumed later. This tutorial contains 2 example problems for you to learn this concept.

Introduction to Rate Order and Rate Laws - Real Chemistry
 
08:02
In this video you will be introduced to rate laws and learn how to determine an overall reaction order. You will also learn how to determine the units of a rate constant, k, for different rate laws. For example, you will learn that the decomposition of hydrogen peroxide is a 1st order reaction. This means that doubling the concentration of hydrogen peroxide will double the rate of the reaction. Because it is a 1st order reaction, the units for the rate constant will be per second. On the other hand, the decomposition of butadiene is a second order reaction. This means that doubling the concentration of butadiene quadruples the rate of decomposition. Since it is a second order reaction, the units of k are per s per M. Lastly we will look at the reaction of hydrogen gas with nitrogen dioxide. This reaction is second order with respect to nitrogen dioxide and first order with respect to hydrogen. To get the overall rate order we simply add together 2 (from nitrogen dioxide) and 1 (from hydrogen) to get 3, the overall rate order.

This chemistry video tutorial provides a basic introduction into elementary reactions and elementary rate laws. It explains the difference between unimolecular, bimolecular, and Termolecular reactions. An elementary reaction is one in which the rate law can be written from the coefficients of the balanced chemical equation and agrees with empirical data. A unimolecular reaction is a reaction that can proceed using a single molecule. A bimolecular reaction is one in which two molecules must collide in order to react. Termolecular reactions require the collision of three molecules.

NO2 (g) + CO (g) → NO (g) + CO2 (g) The initial rate of the reaction is measured at several different concentrations of the reactants with the following results: From the data, determine: (a) the rate law for the reaction (b) the rate constant (k) for the reaction Q2. Consider the following reaction: CHCl3 (g) + Cl2 (g) → CCl4 (g) + HCl (g) The initial rate of the reaction is measured at several different concentrations of the reactants with the following results: From the data, determine: (a) the rate law for the reaction (b) the rate constant (k) for the reaction ANALYSIS: Begin by examining how the rate changes for each change in concentration. Between the first two experiments, the concentration of NO2 doubles, the concentration of CO stays constant, and the rate quadruples, suggesting that the reaction is second order in NO2. Between the second and third experiments, the concentration of NO2 stays constant, the concentration of CO doubles, and the rate remains constant (the small change in the least significant figure is simply experimental error), suggesting that the reaction is zero order in CO. Between the third and fourth experiments, the concentration of NO2 again doubles, the concentration of CO halves, yet the rate quadruples again, confirming that the reaction is second order in NO2 and zero order in CO. Write the overall rate expression. ALTERNATIVE APPROACH If the relationships between the changes in concentrations and the changes in initial rates are not immediately obvious, you can determine the reaction order for any reactant by substituting any two initial rates and the corresponding initial concentrations into a ratio of the rate laws to determine the order (n). For NO2 use the first and second concentrations and rates (because [NO2] changes here, but [CO] is constant). Substitute the rates and concentrations into the expression for the ratio of the rate constants. Take the log of both sides of the equation and solve for n. For CO, use the second and third concentrations and rates (because [CO] changes here, but [NO2] is constant). Substitute the rates and concentrations into the expression for the ratio of the rate constants. Take the log of both sides of the equation and solve for n. Write the overall rate expression from the orders of each reactant. (b) To determine the rate constant for the reaction, solve the rate law for k and substitute the concentration and the initial rate from any one of the four measurements. In this case, you use the first measurement.

MIT 5.111 Principles of Chemical Science, Fall 2014 View the complete course: https://ocw.mit.edu/5-111F14 Instructor: Catherine Drennan Chemists experimentally determine rate laws and then use that experimental information to propose reaction mechanisms. In an overall reaction, some steps will be fast and others slow. One step can be so slow that it governs the overall rate of the reaction; it is the rate-determining step. Learn how to predict reaction mechanisms using the steady-state approximation as well as information about fast and slow steps.

Kinetics 1: Finding the Order, Rate Equation & Rate Constant
 
08:45
Here I look at 3 examples of how the rate equation can be obtained from experimental runs. The order of the reaction for each of the reactants is determined, allowing the rate equation to be constructed. In the third example I rearrange the rate equation to make the rate constant (k) the subject of the equation. I then work out its value and units. In the next video "Kinetics 2" I look at 3 further examples, which are a little more difficult.

Rate Equation and Reaction Mechanism - Kinetics
 
09:33
In this video we want to discuss the relationship between the kinetics rate equation and reaction mechanism. The reaction mechanism is the detailed breakdown of the overall reaction showing each elementary step that is taking place in that reaction. One of these elementary steps is the slowest step and it determines the rate of the overall reaction. Therefore the slow step is also referred to as the rate determining step. The rate determining step is directly related to the rate equation, where the order of reaction with respect to a reactant is the number of that reactant involved in the slow step. Take for instance the following rate equation where order with respect to A and B is 1 and 2 respectively. This means that in the slow step, 1 A and 2 B are involved hence we can write out the slow step as follows: Example 1 Let's try to write out the rate equation given the mechanism as shown: From the slow step there is 1 X and 1 Y as reactants. Therefore order with respect to X and Y are both 1 and the rate equation can be written as follows: rate = k[X][Y] Example 2 Let's have another example: From the slow step there is 1 AB and 1 B as reactants. Therefore order with respect to AB and B are both 1. The rate equation can first be expressed as: rate = k[AB][B] However AB is an intermediate since it is formed in the first step but removed in the second step. Therefore we need to rewrite the intermediate AB in terms of the reactants that forms AB in step 1. Since AB is formed from 1 A and 1 B, we can write it as first order with respect to both A and B. The rate equation will now look like this: rate = k[A][B][B] = k[A][B]^2 So we can conclude the order of reaction with respect to A is 1 and with respect to B is 2.

Reaction Rates, Chemistry & Kinetics, Instantaneous vs Average Rate of Reaction
 
06:23
This chemistry video tutorial provides a basic introduction into reaction rates. The rate of reaction can be calculated from the slope of a concentration vs time graph. The slope of the secant line is equivalent to the average rate of the reaction. You can calculate the slope with the average rate of reaction formula using the data from a graph. The instantaneous rate of reaction over a time interval is equal to the slope of the tangent line. This video is part of the chemical kinetics series. It contains plenty of examples and practice problems of calculating the average rate of appearance of products and the average rate of disappearance of reactants. The production rates of products will always be positive as the reaction proceeds in the forward direction and the rate of consumption of reactants will always be negative.

Is it a Catalyst or an Intermediate? (Given Mechanism)
 
03:15
A catalyst is a chemical that appears as a reactant first, and then as a product. It has been regenerated and doesn't appear in the overall reaction. An intermediate is a chemical that appears as a product first, and then as a reactant. It was produced, but it consumed before the reaction is over. It also doesn't appear in the overall reaction.

Chemical Kinetics 3.4 - Steady-State Approximation
 
06:11
Short lecture on the steady-state approximation for the concentration of reaction intermediates in chemical kinetics. The steady-state approximation says that the change in the concentration of a reaction intermediate over time is zero. This allows us to solve for the time-dependent concentration of the intermediate, and thus determine the overall reaction rate.
