Analysis of the relaxation response induced by various forms of pulse perturbation of coupled chemical equilibria

Abstract

In transient relaxation method studies of fast reactions, if the rate of response of the chemical system is comparable with that of the perturbation, the exact shape of the forcing function must be taken into account in the kinetic treatment of the relaxation response. An analysis of the transient response of multiple coupled equilibria using Laplace transform is presented for various forms of step or impulse perturbation. The method enables one to calculate the relaxation amplitudes for an unrestricted number of coupled chemical equilibria. Various aspects of the analysis of the relaxation response are discussed.
