✦ Synopsis

The natural decay of Fe(phen)33 § where no Ce w is employed for scavenging the side reaction product, Fe(phen)~ +, is now treated as a complex reaction involving two parallel processes, and the experimental kinetics are consistent with the rate laws derived from a mechanism that simultaneously explains the composition of the products as a function of acidity. In terms of the proposed mechanism the dissociation rate of the complex ion in acid solutions containing Ce ~v as scavenging agent is to be regarded as a Ce TM retarded aquation rate, and OH-is to be assigned a catalytic role in the kinetics of basic reduction.

## 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
