Abstract: A reaction kinetic study for electrochemical reduction of nitrobenzene was performed at Cu electrode in H_2SO_4 aqueous solution.The study was carried out on a rotating disc electrode at four different temperatures. Quantitative reaction rates were obtained by di-fferential-conversion experiments and indentified by integral-conversion experiments.Thekinetic expressions represent a simplified schame for cleetroreduction of nitrobenzene to anilineand phenylhydroxylamine,and incorporate the dependence on reactant concentration,temperatureand potential.Results of this paper are suitable for use in reactor design and process moldeling.
