University, Waltair-530 003 Manuscript received 4 July 1980, revised 14 September 1981, accepted 10 December 1981 The kinetics of tile oxidatlon1of \(m\)-cresol by vanadium(V) fn presence of salicylic and substituted salicylic acids was studied in perchloric acid medium.The reaction is first order each in V(V) and \(m\)-cresol. Plots of 1/k2 vs 1/[L](where L represents salicylic or substituted salicylic acid) were found to be linear with positive intercepts on 1/k1-axes, suggesting the formation of a 1 : 1 complex between V(V) and the ligand which is believed to be a more potent oxidant. Tile reaction is acid-catalysed and the plot of l/k1 vs 1/[H+] was found to be linear with a positive intercept on 1/k1-axis. The applicability of Marcus theory to this reaction is discussed.
