Abstract
The kinetics of oxidation of palladium(II) catalysed oxidation of some hydroxyacids viz. malic, citric and tartaric acids by N-bromosuccinim ide have been studied in perchloric acid medium in the presence of mer curic acetate. A first order dependence of rate each in [oxidant] and [catalyst] has been observed. The order of reaction in substrate decre ases at higher [substrate]. A retarding effect of [H+] on the rate has also been observed. A suitable mechanism consistent with observed kin etic data is proposed and discussed.
