Kinetics and Mechanism of Oxidation of Glutaric Acid by Cerium(IV) Ion in Acidic Medium

Chemical Laboratory, D. S. College, Aligarh. Hindu College, Moradabad. Manuscript received 19 September 1977, revised 2 January 1979, accepted 12 March 1979 Kinetic study of oxidation of glutaric acid by Ce(IV) ion in aqueous solution of sulphuric acid shows that the reaction follows first order kinetics in both Ce(IV) and glutaric acid and the over all reaction order ascertained is two. The specific rate constant increases with an increase in the concentration of glutaric acid. Effects of hydrogen ions concentration and temperature have been examined in details. Activation parameters have also been computed. The experimental findings are consistent with the mechanism involving rapid reversible formation of an activated complex between Ce(IV) and glutaric acid followed by a rate determining step involving C—C bond fission
