✦ Synopsis

A kinetic study of the silver(1)-catalyzed oxidation of tris(1,lO-phenanthroline)iron(II) with peroxodiphosphate was carried out by estimating tris-complex at 510 nm. The reaction is found to conform to the rate law (i).

with K2 and K3 being the acid dissociation constants of H~P208-and H~Pz082-, respectively. The silver(1) catalysis in the reaction has been explained on the basis of complex formation between pdp and silver(1).

## Abstract The kinetics of oxidation of several substituted quinols by a series of Tris(1,10‐phenanthroline)iron(III) complexes has been investigated with a stopped‐flow technique at 6.0 and 20.0°C. The reactions were found to be first order on both reactants and independent of acidity. The second

The kinetics of the oxidation of water with bismuth(V) in presence of silver(1) has been investigated in a mixture of HC104 (1.0 mol dm-3) and H F (1.5 mol dm-3). The reaction is second order, viz., first order with respect to bismuth(V) and silver(I1, each, and the second order rate constant is (6.
