摘要：

The kinetics of oxidation of the Co(II) complexes, [Co-II(ADA)(Gly)(H2O)(3)](-) by benzoyl peroxide (BPO) to Co(III) has been followed spectrophotometrically where, [ADA=N-(2-Acetamido imino-diacetato), Gly=Glycinate] over 30-50 degrees C and a variety pH 7.9-8.8 range. The reaction of oxidation of [Co-II(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={(k(3)+k(4)[H+])/[H+])+([H+]/(k(5)+k(6)[H+])}[Co-II(ADA)(Gly)(H2O)(3)](-)[Gly] In the oxidation of [Co-II(ADA)(Gly) (H2O)(3)](-) the rate-determining obeys substitution of one coordinated water molecule by glycinate. The thermodynamic activation parameters have been calculated.
