摘要：

The title reaction provides the first indirect kinetic evidence for the well known assumed complex formation between S2O82- and Ag+. It is al so the first report of a reaction with comparable rates of oxidation of hyponitrous acid and water in the (S2O82 + Ag+) system. Hyponitrous acid is the first reported substrate which is not oxidised by SO4-. Peroxodisulphate ion and hyponitrous acid react in presence of silver(I) as in (i) 5S2O82- + 1.5H2N2O2 + 5H2O --> 10HSO4- + 3HNO2 + O2 ... (i) according to the rate law (ii), -d[S2O82-]/dt = (k0 + 3k1k3[H2N2O2] / k2+k3[H2N2O2])[S2O82-][Ag(I)] ... (ii) k0 and k1 were found to be (4.2 +/- 0.2) X 10(-3) and (5.0 +/- 0.2) X 10(-3) mol-1 dm3 s-1 at 25-degrees and I = 0.11 mol dm(-3).
