The oxidation of glycine and alanine by bis(dihydrogen-tellurto)argentite(III) ion was studied by stopped-flow spectrophotometery. The reaction is of first order in Ag(III) complex and has less than unit order in glycine and alanine. A plausible mechanism was proposed form the kinetic studies. The rate equations derived from mechanism found to explain all experimental phenomena. The activation parameters with respect to the rate determining step of the mechanism were calculated.
