Resumo:  In this paper, the dynamics of electrode reactions under diffusion-migration control is analyzed with an approach based on random walks. The main advantage of this approach is the simplicity of the concepts involved which lead to very simple computational algorithms, avoiding the resolution of differential equations. The model was employed to obtain the profile concentrations of reversible electrode reactions, as well as current transients, for the case where diffusion and migration have comparable effects.
