Abstract

A theoretical model for pulse polarographic response of surface redox reaction followed by totally irreversible, first-order chemical reaction is developed. Adsorption of both the reactant and the product and reversible redox reaction are assumed. The model is tested on benzidine rearrangement of electrochemically produced hydrazobenzene in 3 M HCIO4 in 20% v/v aqueous acetonitrile. The rate constant log(fe /s-1) = 2.2 ± 0.2, referred to E* = -0.006 V vs. Ag/AgCl/4 M NaCl, is obtained.
