Kinetics of oxidation of glycine by permanganate in presence of Palladium(II) catalyst was studied spectrophotometrically. It was found that the reaction exhibits first order dependence on [catalyst] & [oxidant] and less than unit order in [glycine] and [alkali]. The data suggests that oxidation proceeds via formation of a complex between the substrate and the catalyst, which than reacts with one mole of permanganate in a slow step to form a glycine free radical followed by a fast step to yield the products. The activation parameters of the rate determining step were computed and are discussed. The reaction constants involved in the mechanism were calculated and there is good agreement between observed and calculated rate constants under different experimental conditions.
