Abstract

The kinetics of formation of the [PVA. Mn^VI^O] 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]/d__t__ = k~1~[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.

## Abstract The kinetics of decomposition of [PVA. Mn^VI^O‐] intermediate complex have been studied spectrophotometrically. A first‐order dependence on the intermediate concentration was observed. The decomposition rate was found to be base‐catalysed. The kinetic parameters have been evaluated and
