Collision Theory Model, Rates of Reaction, Activation Energy, Arrhenius Equation - Chemical Kinetics
 
10:45
This chemistry video tutorial provides a basic introduction into the collision theory model. In order for two molecules to react, they must collide with sufficient energy and with the proper molecular orientation. This video describes the relationship of the rate of the reaction with temperature and activation energy using the arrhenius equation. As the temperature increases, the rate constant k increases, which in turn increases the rate of the reaction. Whenever a catalyst is added, the activation energy decreases which increases the value of the rate constant k which in turn increases the reaction rate. This video also includes a brief discussion into energy diagrams. The forward activation energy is the difference between the energy of the transition state / activated complex and the energy of the reactants. This video is part of the chemical kinetics series. This tutorial also discusses the difference between the collision frequency, steric factor, and the frequency factor in the arrhenius equation.

Note that the IB definition of the Arrhenius constant (A) indicates the frequency of collisions and the probability that collisions have proper orientations. Understandings: The Arrhenius equation uses the temperature dependence of the rate constant to determine the activation energy. A graph of 1/T against ln k is a linear plot with gradient – Ea / R and intercept, lnA. The frequency factor (or pre-exponential factor) (A) takes into account the frequency of collisions with proper orientations.

The decomposition of ozone is important to many atmospheric reactions. O3 (g) → O2 (g) + O (g) A study of the kinetics of the reaction resulted in the following data: (a) Determine the value of the frequency factor and activation energy for the reaction. Gas constant: (8.314 J/(mol⋅K)   where 1 J=1 (kg ⋅ m^2)/s^2 ) (b) Use the results of the Arrhenius analysis to predict the rate constant at 298 K. Solution: To determine the frequency factor and activation energy, prepare a graph of the natural log of the rate constant (ln k) versus the inverse of the temperature (1 ∕ T). The plot is linear, as expected for Arrhenius behavior. The best fitting line has a slope of −1.12 × 104 K and a y-intercept of 26.8. Calculate the activation energy from the slope by setting the slope equal to −Ea ∕R and solving for Ea: Calculate the frequency factor (A) by setting the intercept equal to ln A. 26.8 = ln A A = e26.8 = 4.36 × 1011 Since the rate constants are measured in units of M−1 • s−1, the frequency factor has the same units. Consequently, we can conclude that the reaction has an activation energy of 93.1 kJ ∕ mol and a frequency factor of 4.36 × 1011 M−1 • s−1.

29:26
The Arrhenius Equation is discussed. In order to better discuss the different parts of this equation an example chemical reaction is looked at; the unimolecular isomerization reaction of methylisocyanide forming methylcyanide. The kintics are discussed and the reaction profile is studied. The activation energy is discussed along with how it relates to the transition state structure. The frequency factor is related to the vibrational character of the reactant molecule - the frequency of vibrations, or how often the vibrations occur. And the temperature is related to the magnitude of vibrations. The exponential factor is then related to the fraction of molecules with enough energy to overcome the activation energy barrier. The difference between the frequency factors unimolecular and bimolecular reactions is briefly discussed. Finally an example is done in which experimental data consisting of rate constants determined at different temperatures is used to determine the activation energy and frequency factor.

Chemical Kinetics Made Easy: Reaction Rates and Temperature The Arrhenius Equation Episode #07
 
14:35
Chemical Kinetics Made Easy: Reaction Rates and Temperature The Arrhenius Equation Episode #07 Chemical kinetics, also known as reaction kinetics, is the study of rates of chemical processes. Chemical kinetics includes investigations of how different experimental conditions can influence the speed of a chemical reaction and yield information about the reaction's mechanism and transition states, as well as the construction of mathematical models that can describe the characteristics of a chemical reaction. In 1864, Peter Waage and Cato Guldberg pioneered the development of chemical kinetics by formulating the law of mass action, which states that the speed of a chemical reaction is proportional to the quantity of the reacting substances. Van 't Hoff studied chemical dynamics and published in 1884 his famous "Etudes de dynamique chimique". In 1901 he was awarded by the first Nobel Prize in Chemistry "in recognition of the extraordinary services he has rendered by the discovery of the laws of chemical dynamics and osmotic pressure in solutions". After van 't Hoff, chemical kinetics deals with the experimental determination of reaction rates from which rate laws and rate constants are derived. Relatively simple rate laws exist for zero order reactions (for which reaction rates are independent of concentration), first order reactions, and second order reactions, and can be derived for others. Elementary reactions follow the law of mass action, but the rate law of stepwise reactions has to be derived by combining the rate laws of the various elementary steps, and can become rather complex. In consecutive reactions, the rate-determining step often determines the kinetics. In consecutive first order reactions, a steady state approximation can simplify the rate law. The activation energy for a reaction is experimentally determined through the Arrhenius equation and the Eyring equation. The main factors that influence the reaction rate include: the physical state of the reactants, the concentrations of the reactants, the temperature at which the reaction occurs, and whether or not any catalysts are present in the reaction. Gorban and Yablonsky have suggested that the history of chemical dynamics can be divided into three eras. The first is the van 't Hoff wave searching for the general laws of chemical reactions and relating kinetics to thermodynamics. The second may be called the Semenov--Hinshelwood wave with emphasis on reaction mechanisms, especially for chain reactions. The third is associated with Aris and the detailed mathematical description of chemical reaction networks.
