| Summary: | Theory is presented describing how the effective number of electrons transferred during a DISP1 process at a channel electrode depends on the electrolyte flow rate and the rate constant for the first order chemical step. It is shown that a DISP1 process can be distinguished from an ECE process provided an independent determination of the rate constant for the chemical step is made and that this is conveniently done using ESR transients obtained by stepping the current of the channel electrode positioned at the centre of an ESR cavity. Experiments with the semi-fluorescein radical anion are shown to be in excelient agreement with theory. |
