Abstract: The rapid kinetics of chlorination of isomers of nitrophenol in aqueous solution by molecular chlorine in KNO3 as supporting electrolyte has been studied using the rotating platinum electrode (RPE). The specific reaction rate (k), energy of activation (Ea), free energy change of activation (G*), enthalpy change of activation (H*), entropy change of activation (S*) were evaluated. The reaction was found to be rapid and of the second order. The rapidity of the reaction necessitated the use of a special technique RPE. The diffusion current of unreacted chlorine in the reaction was measured. Thus, the present work provides the quantitative verification of the reactivity of the electrophile in the reaction.
