It has been considered that the analysis of the current density-overpotential curve for the quasireversible electrode system would be complicated, while that for the reversible and irreversible ones could be done approximately by using the reduced forms of the general expression which represents the steady-state current flowing at the electrode under an overpotential.In this report, it is shown that if the anodic and cathodic diffusion-limited current densities were given for a quasi-reversible electrode system by some proper method, the activation and concentrationoverpotentials under a polarization of the electrode could be determined so that the current densityoverpotential curve would be analyzed explicitly by the general expression, resulting in the estimation ofthe exchange current density and the transfer coefficient. This approach is applied to analyze the current density-overpotential curve for an anodic dissolution of the (111) surface of copper single crystal in a concentrated solution ofNaCI containing NaBr and a small amount ofCuCl, and proved reasonable.
