Below the limiting current, the rotating disk electrode has a nonuniform current distribution. When the nonuniforrnities are not explicitly accounted for, errors in values of kinetic parameters determined through measurements on a disk can result. In this analysis, valid for Tafel kinetics, correction factors are obtained as a function of the dimensionless average current density. It is assumed that ohmic corrections are made by the interruption of current. The results indi-cate that, under certain conditions, the errors are negligible and that the disk geometry, despite its nonuniformities, is adequate for the investigation of systems characterized by Tafel kinetics.
