Abstract

Kinetics of redox reaction between I- and [MnIII(cdta)]- has been investigated in aqueous solution by a stopped-flow technique at pH 3.26 (acetate buffer) and at 30, 35 40 and 45°C. The overall reaction is third order - first order in [MnIII(cdta)-] and second order in [I-]. Though no direct evidence has been obtained, an inner-sphere mechanism has been proposed based on the lability of the complex and is supported by the large negative value of ΔS# (-168 ± 6) JK-1 mol-1.
