Abstract: The oxidation of citric and malic acids by bromate in acidic aqueous solutions is catalysed by aquachlororuthenium complex and the kinetics of the reaction is investigated. The rate law is interpreted by a mechanism involving the oxidation of Ru(lll) to Ru(V) by oxidant (Kt), followed by a complex formation (Kc) between Ru(V) and substrate, which decomposes (kd) to products in a slow rate determining step with regeneration of Ru(lll). All individual rate constants are determined at different temperatures and their activation parameters are also evaluated and discussed.
