Abstract
Two electrode reactions that are coupled by a chemical reaction are called an ECE mechanism. The model of this mechanism which has an unstable intermediate is developed for staircase voltammetry on the rotating disk electrode. It is assumed that both electrode reactions are fast and reversible and that the chemical reaction may appear to be of the second order and reversible. The influence of the concentration of an electro-inactive component of the chemical reaction is investigated, and the conditions under which the reaction turns into the first order one, and becomes totally irreversible, are reported.
