Coupled homogeneous electrode reactions theoretical treatments

Besides its obvious application to preparative electrolysis, controlled-potential electrolysis (CPE) also can aid in mechanistic analysis of the electrode reaction. The treatment of coupled chemical reactions is simpler theoretically in CPE than in most other electrochemical methods, because the solution can be treated as being homogeneous, rather than having to account for concentration changes as a function of distance from the electrode. The mathematics are more straightforward.
