The earlier study D. A. Flanders and H. Fricke, J. Chem. Phys.28,1126 (1958) of the kinetic properties of a cylindrically symmetric one radicalhyphen;one solute model was extended by taking account of the transient dilution of the solute which occurs during the reaction. The results of the computations are collected in a table from which, by interpolationIRthe fraction of radicals recombining, can be obtained for any experimentally important values of the four dimensionless parameters which define the problem. Under conditions of practical interest the effect of solute depletion on IRis (a) appreciable only when the ratio of the rate constants of radicalhyphen;solute and radicalhyphen;radical reactions is above 0.1, and (b) only slightly affected by the diffusion coefficient of the solute. The role played by solute depletion is elucidated by graphs representing the transient course of the reactions.
