Abstract

The kinetics of tartaric acid oxidation by peroxodisulphate ion has been studied to elucidate the mechanism of oxidation. Uncommon to many peroxodisulphate reactions it shows a variation in order. It is found to progress bimolecularly in the beginning and unimolecularly till completion. H^+^ ion and O~2~ gas accelerate the reaction. Some observations with change of surface revealed that area/volume ratio Influences the rate of reaction. In order to explain the observed data the chain mechanism has been proposed and rate expressions have been derived to explain the change of order from two to one.

The reaction has been studied spectrophotometrically monitoring the absorbance in the wavelength range. The spectra of the reactants, intermediates, and prod-240-400 nm ucts in this system are overlapping; thus special programs [1,2] have been used (and tested) to unravel the kinetics and mechanism

The kinetics of oxidation of N,N-dimethylformamide by chromium(VI) has been studied spectrophotometrically in aqueous perchloric acid media at 20ЊC. The rate showed a first-order dependence on both [Cr(VI)] and [DMF], and increased markedly with increasing [H ϩ ]. The order with respect to [HClO 4 ]
