Abstract
An extension is presented, of the theory of a chronoamperometric experiment for an ErevC′rev catalytic reaction mechanism with a reversible charge transfer and a pseudo-first order reversible homogeneous reaction at a planar electrode. Diffusion transport is assumed. The extension refers to the case when (simultaneously) diffusion coefficients of the members of a redox couple are unequal, and the homogeneous reaction is reversible. For such a case no analytical nor semi-analytical solutions were available thus far. Non-trivial expressions, involving doubly nested complex square roots, are derived for the Laplace transform of the nonlimiting Faradaic current. They are inverted numerically. The results obtained should be of interest in the studies of homogeneous redox catalysis for electrochemical energy sources.
