A basic kinetic equation of potential-step chronoamperometric current-time curve controlled by the rates of diffusion and electron transfer for a simple one-electron charge transfer reaction was given and various
features of current-time curves were deduced from a
theoretical treatment. The current-time equations for
reversible and irreversible electron transfer processes appear as special cases with limited conditions of the
equation reported in the present paper. And a potential-step chronoamperometric method to determine kinetic parameters from a current-time curve was proposed therefrom. The extension of a basic kinetic equation to more general multistep charge-transfer process was also considered.
