Kinetics and mechanism of electron-transfer reactions: ruthenium(III) chloride catalyzed oxidation of aspartic acid by peroxomonosulfate ion in acidic medium

The kinetics of the oxidation of aspartic acid by peroxomonosulfate catalyzed by ruthenium(III) chloride was studied in acidic medium. The stoichiometry of the reaction corresponds to a reaction in which a mole of the amino acid reacts with a mole of peroxomonosulfate ion. A plausible reaction mechanism has been suggested and the derived rate law accounts for all experimental observations. Activation parameters have also been evaluated.
