Electrode Kinetics at Open Circuit at the Streaming Mercury Electrode I. Theory

摘要

A general equation is derived for the potential, at open circuit, of an electrode of varying area at which a charge transfer process occurs. Application is made to the streaming mercury electrode for which there is continuous renewal of the double layer. The steady-state overvoltage is derived for mixed control by charge transfer and mass transfer for any value of the overvoltage. Simplified equations are given for small overvoltages (
