| Abstract: | Kinetics of copper ion catalysed peroxydisulphate oxidation of glyoxylate has been investigated in the pH range 3.6 to 5.4 and ionic strength of 0.2 to 0.5 M. The reaction is first order each in the concentrations of glyoxylate, peroxydisu lphate and Cu2+. The rate is invariant with pH indicating that glyoxylate and glyoxylic acid do not differ in reactivity. Kinetic result, are consistent with a mechanism involving a complex formed between catalyst, substrate and oxidant species on the rate-limiting process. The rate and activation parameters of the reaction have been evaluated. High positive entropy of activation is in keeping with the formation of more number of product species and less effective solvation of the transition state. |
