| Abstract | ||
| Kinetics of oxidation of p-anisidine by Fe(III) ion was studied spectrophotometry in acidic medium. The rate constant was found to increase with increasing p-anisidine and hydrogen ion concentrations. The order of reaction was found to be first order with respect to both Fe(III) ion and p-anisidine concentration. The suggested mechanism involves the interaction of the reactive species of the reactants to form the activated complex which decompose in a rate determining step to products. The rate law was derived and activation parameters are calculated to be H* = 47 kJ mol-1 and S* = -148.6 JK-1 mol-1 | ||
