Abstract
Publisher Summary This chapter presents the studies related to the molecular properties of the reaction system known as molecular kinetics. There are several aspects to a kinetic study. One of these aspects is concerned with the phenomenological, or empirical, rate laws that are obeyed. A second important type of kinetic study relates to the way in which rates depend on temperature. A third important aspect of kinetics is concerned with the elucidation of complex reaction mechanisms on the basis of kinetic and other studies. These various types of kinetic aspects are closely related to one another, and molecular kinetic studies are very valuable in arriving at conclusions about reaction mechanisms. One of the most important relationships in chemical kinetics, and one that provides much information as to mechanism, is the one that connects the rate constant of a reaction with the temperature. A reaction tends to show a strong isotope effect if in the rate-controlling step, the bond to the labeled atom is broken or considerably weakened.
