ABSTRACT:
Kinetics and Mechanism of uncatalysed oxidation of D-ribose by cerium (IV) in aqueous acidic medium have been investigated titrimetric method in the temperature range 308-333K. The reaction has been found to be first order with respect to D-ribose in an uncatalysed reactions. The effect of [HSO4-] has also been observed. The increase in ionic strength of the medium decreases the rate of uncatalysed reaction. A 1:2 stoichiometry is observed in the oxidation reaction. On the basis of the experimental results, a reasonable mechanism has been proposed. Rate equation derived from this mechanism can explain all the experimental results. From the effect of temperature on the reaction rate, the Arrhenius equation and various activation parameters have been computed.
