Faradaic rectification: an amended treatment—II. Experimental verification

Abstract

The conclusions arrived at in Part 11 of this series have been verified experimentally with Cd2+/Cd(Hg) in M NaClO 4, Fe2+/Fe3+ in M oxalate and Cd2+/Cd(Hg) in M KCl. The numerical method leads to values of the rate constant ksh that agree with those obtained by graphical extrapolation only if the reaction is rather irreversible. In the case of fast reactions the classical extrapolation method is shown to lead to serious errors.
