Kinetics of oxidation of potassium thiocyanate by the oxidant chloramine-T (CAT) in presence of NaOH has been studied at 30 °C. At low substrate concentrations, the approximate rate law is, — d[CAT]/dt = k[CAT][KNCS]/[NaOH]2. At higher substrate concentrations, the rate law simplifies to, —d[CAT]/dt = k[CAT]/[NaOH]. Ionic strength and addition of p-toluene sulphonamide have negligible influence on the rate. The rate of reaction decreases in D2O medium and the value of the inverse solvent isotope effect, kH2o/kü2o is 0.46. The reaction has been studied at different temperatures and the activation parameters have been calculated.
