A theoretical model of electrocatalytic mechanism that is determined by Michaelis-Menten kinetics is developed for cyclic voltammetry. The adsorption and desorption of product of catalysis is considered and its influence on voltammograms is investigated. The rate constants of catalytic reaction and dissociation of the product from the surface can be estimated from the linear relationship between inverse limiting current and inverse concentration of substrate.
