Electrochemical reactions where the variation of supporting electrolyte concentration is mechanistically revealing: ECE-DISP1 processes in which the chemical step is an isomerisation

Abstract:

The variation of supporting electrolyte concentration so that the relative contribution of migration and diffusion to transport is altered has been shown to be mechanistically revealing in some cases. We consider the following ECE/DISP1 mechanism, in which the chemical step, B C, is an isomerisation: A+e-BBCB+CA+PC+e-PThis system is studied by simulating voltammetric responses at a hemispherical microelectrode over a range of scan rates and support ratios. A wide range of rate constants for t...
