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. They want to determine the rate at which a reaction mixture approaches the state of its equilibrium, yielding a certain reaction product. This rate can be enhanced by changing the concentration of reactants and the pressure, by temperature increase, or by various catalysts. A more sophisticated reason, which is presently of our primary interest, is the study of reaction mechanisms, that is, the determination of those elementary reaction steps which finally lead to the reaction product. This book is to teach students how to come up with reasonable mechanisms for reactions that they have never seen before. As most chemists know, it is usually possible to draw more than one reasonable mechanism for any given reaction.
