Abstract

AbstractThe sources of error pertaining to the oscilloscopic determination of rate constants of electrode reactions are studied and the upper and lower limits of the methods are given. The former is mainly determined by the accuracy with which the moment of zero diffusion polarization can be adjusted.It is shown that the extrapolation of cell responses to zero frequency does not eliminate the contribution of the double layer capacitance completely. The remaining contribution is a negative resistance,‐2 σ2 Cd, irrespective of waveform.
