Abstract
Theoretical rotating ring and disk electrodes voltammograms are discussed for a process consisting of two consecutive charge transfer steps under steady‐state conditions. The relationship between total disk current, , and ring current,, is examined. Plots of vs. the reciprocal of the square root of the rotation rate, , are classified into three cases depending on the reversibility of the second charge transfer step. Although the voltammograms of the disk electrode may be those of a single wave, a distorted s‐shape, or a well‐separated two step, the ratio is not affected by the kinetic parameters of the first charge transfer step, except for the number of electrons.
