Abstract
The kinetics of oxidation of the Co(II) complexes, [CoII(ADA)(Gly)(H2O)3]- by benzoyl peroxide (BPO) to Co(III) has been studied spectrophotometrically where, [ADA=N-(2-Acetamido imino-diacetato), Gly=Glycinate] over 30-50oC and a variety pH 7.9-8.8 range. The reaction of oxidation of [CoII(ADA)(Gly)(H2O)3]- by benzoyl peroxide was studied under pseudo-order kinetic conditions with respect to complex and it obeys the following rate law:



Rate={(k3+k4[H+])/[H+])+([H+]/(k5+k6[H+])}[CoII(ADA)(Gly)(H2O)3]-[Gly]



In the oxidation of [CoII(ADA)(Gly) (H2O)3]- the rate-determining obeys substitution of one coordinated water molecule by glycinate. The thermodynamic activation parameters have been calculated.
