ABSTRACT:
A kinetics investigation of catalysed oxidation of D-(+) ribose by cerium(IV) have been studied in acidic medium in the temperature range 308-333 K. The reaction has been found to be first order with respect to D-(+) ribose in the presence of La(III) catalysed. The rate follow first order kinetics in La(III) catalysed oxidation reaction. The effect of [HSO4-] has also been observed. The 1:2 stoichiometry is observed in the oxidation. From the effect of temperature on the rate of reaction , the Arrhenius equation and various activation parameters have been computed. A suitable mechanism has been proposed and a rate law explaining the experimental observations is derived.
