Abstract

The rate of a catalytic reaction is determined by the dynamics of the individual steps involved, which may be classified according to a rough hierarchy: The quantum level concerns the energy exchange between the different degrees of freedom. If these are in thermal equilibrium at all stages, the concepts of transition state theory may be applied to formulate the rates of the elementary processes constituting the reaction mechanism. Combination of these steps eventually enables rationalization of the macroscopic kinetics. The contributions of surface science to the current knowledge of the various levels of these complex phenomena are illustrated by selected examples.
