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

► We study ECE/DISP1 reactions at a hemispherical electrode. ► The chemical step considered is an isomerisation. ► The effect of supporting electrolyte concentration is investigated. ► Varying supporting electrolyte concentration can lead to mechanistic resolution.
