The kinetics of formation of the [PVA. MnVIO ] intermediate complex have been measured by the conventional spectrophotometric technique. The rate of formation of the complex was found to be given by the expression d[Complex]/dt = k1[MnO‐4][PVA−]. The results showed that the rate of formation is dependent on the base concentration. A first‐order reaction in permanganate and fractional order with respect to the poly(vinyl alcohol) (PVA) concentration were observed. The activation parameters have been evaluated and a tentative reaction mechanism has been suggested.
