Abstract
Oxidation of ascorbic acid (AH2) by ruthenium(lII) has been
investigated kinetically in acidic medium, which indicated a first
order dependence with respect to ascorbic acid and ruthenium(III)
and an inverse order dependence with respect to hydrogen ion concentration.
An insignificant effect on the reaction rate was observed
with a change in ionic strength. Energy of activation and entropy
of activation have been calculated and an appropriate mechanism
consistent with the experimental data has also been formulated.
