An interfacial Process For o+ne=R 5 separate events must occur O must be successfully transported from bulk solution(mass transport) O must adsorb transiently onto electrode surface (non-faradaic) CT must occur between electrode ando (faradaic) R must desorb from electrode surface(non faradaic) R must be transported away from electrode surface back into bulk solution(mass transport)An Interfacial Process • For: O + ne- = R • 5 separate events must occur: – O must be successfully transported from bulk solution (mass transport) – O must adsorb transiently onto electrode surface (non-faradaic) – CT must occur between electrode and O (faradaic) – R must desorb from electrode surface (non￾faradaic) – R must be transported away from electrode surface back into bulk solution (mass transport)
