Abstract
A theoretical model for pulse polarographic response of surface redox reaction followed by totally irreversible, first-order chemical reacti on is developed. Adsorption of both the reactant and the product and r eversible redox reaction are assumed. The model is tested on benzidine rearrangement of electrochemically produced hydrazobenzene in 3 M HCl O4 in 20% v/v aqueous acetonitrile. The rate constant log(k/s-1) = 2. 2 +/- 0.2, referred to E = -0.006 V vs. Ag/AgCl/4 M NaCl, is obtained .
