  • Since the concentration of an electroactive substance at the electrode-solution interface decreases mono- tonically, the faradaic current due to its electrooxidation or electroreduction increases monotonically with time because of the increasing concentration gradient of the electroactive substance, the concentra- tion of which remains constant in the bulk. The maximum current value is passed when the transport rate of electroactive substance to the electrode-solution interface starts to be lower than the rate at which it is removed by reaction at the electrode. The result of these two competing processes leads to the peak- shaped I-E dependence. [en]
