Theory of Absolute Rates of Gas/Solid Interface Reactions

The discussed results yielded from development of the absolute reaction rate theory for surface processes, which was initiated by works of M. I. Temkin on uniform and nonuniform solid surfaces. His works also studied the interaction effect of adsorbed particles to the kinetics of surface reactions and discussed several adsorption sites blocked by adsorbed particles, kinetic complications caused by low mobility of adsorbed particles, and effect of high pressures in gas phase. At the present time, the theory of surface processes provides simultaneous account of all the major physical factors: nonuniform surface, interaction of adsorbed particles, size of particles, limited mobility of reagents, and rearrangement of surface. This review analyzes the role of self-consistent description of elementary reaction rates and equilibrium reaction system, which was emphasized by M. I. Temkin. The self-consistency requirement for dense surface phases, which realize cooperative behavior of reagents, indicates to the restrictions of the earlier derived kinetic equations.
