Abstract

Kinetics and mechanism of oxidation of leucine and alanine by AgIII complex were studied spectrophotometrically in alkaline medium at constant ion strength. The reaction was in first order with respect to AgIII complex and amino acids leucine, alanine. The second-order rate constant, 𝑘−, decreased with the increasing in OH− and IO4−. A plausible mechanism was proposed from the kinetics study, and the rate equations derived from mechanism can explain all experimental phenomena. The activation parameters were calculated at 298.2 K.
