A method is described for the study of the kinetics of electrode reactions on the basis of analytical solutions of three transient electrochemical processes comprising the diffusion of ions in electrolyte, charge-transfer reactions, and a charging process of an electrochemical double layer. Multipulse currents are applied to a working electrode of (110) single-crystal line nickel in nickel sulfamate, and the potentials between the working and counter electrodes are recorded. The measured potential-time curves well agree with those predicted by the analytical solution. The kinetic constant, exchange current density, and double-layer capacitance characterizing the kinetics of the electrode reactions are determined from the measured potential-time curves using the analytical solution.
