Redox reaction of the ¬¬glutamic acid, (Glu) and synthesized bis[bis(ethylenediamine)succinimidato-cobalt(III)]dinitrate dehydrate, (suc)(en)2Co(µ-O2)Co(en)2(suc)](NO3)2.2H2O hereby referred Co(O2)Co2+ has been studied in aqueous hydrochloric acidic medium at wavelength 420 nm and temperature 27 ± 1oC. The rate shows first order dependence each on Co(O2)Co2+, [Glu], and [H+]. The overall rate equation for the reaction can be shown below: Michaelis-Menten plot is linear and passes through the origin and spectroscopic studies indicate no significant shift from the absorption maximum characteristic. Variation of the ionic strength in the range 1≤I≤1.2 mol dm-3 indicates a positive Bronsted-Debye salt effect. The rate laws proposed is in agreement with the experimental results discussed and an outersphere mechanistic pathway is probably in operation in this reaction.
