3. Theoretical morphology of current-potential characteristics

3.1 Principle for establishing the electrode current-potential relationship

We saw in the article that the equation expressing the speed of the process at the – electrode as j = f (E) – involves the concentrations $c_i^{\ast }$ of the reactants at the electrode surface (where charge transfer takes place). These concentrations are variable during voltammetric exploration, and are linked to the value of j and to the concentrations $c_i^{\circ }$ outside the diffusion layer by equations expressing...
