| Abstract: | Kinetics and mechanism of oxidation of 1,4‐butanediamine by a Ag(III) complex were studied spectrophotometrically in alkaline medium at constant ion strength. The reaction shows first order with respect to the Ag(III) complex and 1,4‐butanediamine respectively. The second order rate constant, k′, increased with the increasing in OH?], and decreased with the increasing in IO4?]. A plausible mechanism was proposed from the kinetics study. The rate equations derived from the mechanism can explain all experimental phenomena. The activation parameters were calculated. |
