Theory of Square-wave Voltammetry of Kinetically Controlled Two-step Electrode Reactions

An influence of electron transfer kinetics on square-wave voltammograms of two-step electrode reaction is investigated theoretically. A phenomenon of "kinetic burden" of potential inversion is de- scribed for the case of equal kinetic parameters. A linear relationship between standard rate constant and the difference between standard potentials of the second and the first charge transfers is demonstrated for the reactions with thermodynamically unstable intermediate.
