Abstract : Electrode processes for the oxidation of some low molecular w ight organic compounds at platinum electrodes in 2N sulfuric acid and 2N sodium hydroxide solutions were studied. Cyclic voltammetry, chronopot iometry, potential decay, and controlled potential oxidation were used. A new method for studying the kinetic order of electrode reactions was used. At low organic-compound concentrations, the rate of electrolytic oxidation of the organic compound is first order with respect to the concentration of the organic compound and first order with respect to the surface area of the electrode; at higher concentrations, an equilibrium reaction is observed. It w s concluded that his equilibrium reaction is adsorption of the organic molecules on the platinum electrode and that adsorption is the ratedetermining step of the oxidation reaction. (Author)
