Abstract

The kinetics of oxidation of β-alanine by the Ag(III) complex has been studied by spectrophotometry. The reaction is first order with respect to the Ag(III) complex. The values of k obs decrease with an increase of [OH−], and then increase with the increase of [OH−]. The concentration of OH− was 0.03 mol · L−1 at the turning point at which the rate was the slowest. A plausible mechanism of reaction is proposed, and the rate law has been obtained, which could be applied to explain all experimental phenomena. The activation parameters of the rate-determining step have been also calculated.
