  Abstract:   The oxidation of malic acid by N-chloronicotinamide in the presence of HClO4 is studied. First order kinetics with respect to NCN is observed. The kinetics results indicate fractional order in hydroxy acid. Rate of the reaction increases with a decrease in the percentage of acetic acid. Inverse first order in [H+] and [nicotinamide] are noted. Decrease in the rate constant was observed with the increase in [SDS]. The values of rate constants observed at four different temperatures were utilized to calculate the activation parameters. A suitable mechanism consistent with the experimental findings has been proposed.
