Abstract
The kinetics of the title reaction were determined spectrophotometrically. The oxidation was second order; but first order with respect to both [hexacyanoferrate(III)]0 and [hydrazide]0. The effect of [HClO4] on the reaction rate was curious; as the HClO4 concentration increased the rate decreased and, reaching a minimum. The rate was slightly enhanced by an increase in ionic strength, but was insensitive to added salts, such as NaClO4, NaNO3, NaCl, KCl, Licl and K4Fe(CN)6 at constant ionic strength. Addition of MeOH retarded the oxidation rate and the entropy of activation was negative. Carboxylic acids and N2 were identified as the oxidation products. A radical mechanism and a rate law consistent with the experimental results is proposed.
