2 Reaction Mechanisms 7. Elementary Reactions 8. The Rate Law and the Mechanisms 9. Catalysis Chemical kinetics is the study of reaction rates, how reaction rates change with varying conditions, and what molecular events occur during the overall reaction. The questions explored in this chapter include How is the rate of a reaction measured? What conditions will affect the rate of a reaction? How do you express the relationship of rate to the variables affecting the rate? What happens on a molecular level during a chemical reaction? What variables affect reaction rates? Concentration of reactants.
