Abstract

The concentration of electroactive ions c i which determines the overall kinetics of the electrode process differs in general from the bulk ion concentration. This is a consequence of the location of ion discharge, which is at a potential ψ′, different from the bulk solution potential, as it have been noted earlier. Additionally, at high overpotentials, the rate of discharge is very fast and ion reduction is limited by the rate of transport to the electrode surface. The steady state rate of the electrochemical process is in this case exactly equal to the rate of transport of the electroactive species from the bulk.
