The Arrhenius parameters of the bimolecular rate constants for the decay of several phenoxyl radicals in aqueous solution were measured. The p-halophenoxyl radicals (F, C1, and Br) decay in a diffusion controlled reaction as the activation energies are the same as that of diffusion of water (16 ? 1.
The kinetics of the acqueous-phase reactions of the free radicals .OH, .Cl,, and SO; . with the halogenated acetates, CHzFCOO-, CHF2COO-, CF3COO-, and with CHzClC00-, CHClzC00-, CC13COOwere investigated. Generally, the reactivity decreases with increasing halogen substitution and is in the order k(.
