The kinetic study of oxidation of indole using peroxomonosulphate was carried out in aqueous acetone medium in the temperature variation of 293-308 K. The influence of [indole], [peroxomonosulphate], [H+], ionic strength, percentage of acetone and temperature on the rate of reaction was carried out. The order with respect to [peroxomonosulphate] and [indole] was also one. The total reaction was second order, first order each with respect to [Indole] and [PMS]. No effect of [H+] on the rate was observed while increase of [H+]. Variations of ionic strength had no effect and Increase of percentage of aqueous acetone decreased the rate. Suitable mechanism in conformity with the kinetic observations has been proposed and Activation and thermodynamic parameters have been computed basis of the observed data. The product isatin was confirmed from the IR and NMR spectral analysis.
