Abstract
The kinetics of oxidation of diethylene glycol (DG) by dihydroxyditelluratoargentate(III) (DDA) is studied spectrophotometrically between 298.2K and 313.2K in alkaline medium. A mechanism involving a one–step two–electron transfer has been proposed The activation parameters and the rate constants of the rate-determining step are calculated.

Abstract
Kinetics of oxidation of 1,4-butylene glycol by dihydroxydiperiodatoargentate(III) in alkaline liquid has been investigated by spectrophotometry in the 298.2–318.2K range. The order in oxidant was pseudo first order and the order with respect to 1,4-butylene glycol was 1< nap<2. The associated rate law was: –d[Ag(III)]t/dt = { kK1 K2[OH-][HOCH2CH2CH2CH2OH]2[Ag(III)]t}/{[H2IO43-] + K1[OH-] + K1 K2[OH-][HOCH2CH2CH2CH2OH]} = kobs [Ag(III)]t. A plausible mechanism involving a pre-equilibrium of adduct formation between the complex and reductant was proposed. The activation parameters along with rate constants of the rate-determining step were calculated.
