Under conditions of nondissociative coadsorption of reagents involved in the superficial redox reaction, the main criterial relations of the linear voltammetry method are found to be independent of the isotherm kind and the number of molecules of water or other surface-active, but electrochemically indifferent, particles that are displaced from the electrode surface by adsorbate particles. The concentration dependence of the parameters of the adsorption peak on the anodic voltammetric curve is discussed in detail, as is the relation between the parameters and both the isotherm kind and the change in the number of adsorption sites during the redox reaction.
