The rate of reaction of nitrous acid and 4-aminobenzenesulphonamide in nitric acid

Abstract

On the basis of the competitive reaction of nitrous acid with hydrogen peroxide in nitric acid medium the rate constant of the reaction of 4- aminobenzenesulphonamide with nitrous acid has been determined to be 6.4 l² mol^-2 s^-1 at 22°C and has been found to be independent of nitric acid concentration in the range 0.5-2M.
