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(.
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.
