Abstract
The kinetics of the acetic acid inhibited Co2O3 catalysed autoxidation of S (IV) in alkaline medium has been studied and based on the observed results following rate has been proposed. Rate constants and the order of reaction were calculated and the reaction was found to be pseudo- first order in all cases. The effect of pH and temperature are also discussed. The value of apparent activation (Ea) energy was by Arrhenius equation. On the basis of inhibition parameters the reaction follows free radical mechanism.
