This oxidation has been investigated in the acidity range 1-5 mol dm-3 HClO4 at a constant ionic strength of 5 mol dm-3 over the temperature range 25-60 deg C.The consumption ratio <ΔV>>:<Δ> is found to lie between 1:1 and 2:1 using an excess of VV.With an excess of NH2OH, the reaction is first order in V> and the order in is between zero and one.The variation of the pseudo-first-order rate constant with and +> shows that two pathways operate, one via the complex VO2+*NH3OH+aq. and the other via V(OH)23+*NH3OH+.Values for the overall enthalpy and entropy of activation are determined for each pathway.
