Application of a Highhyphen;Speed Electronic Computer in Diffusion Kinetics. II. Depletion Effect in the Spherical Onehyphen;Radical Onehyphen;Solute Model

摘要

The earlier computations D. A. Flanders and H. Fricke, J. Chem. Phys.28,1126 (1958) on the Spherical Onehyphen;Radical Onehyphen;Solute model were extended by taking account of the transient dilution of the solute which occurs during the reaction. Although the drop in concentration of the solute near the center of the reaction zone may be considerable, its effect on the fraction of radicals combining with the solute is only of the order of one percent under the most unfavorable conditions likely to be encountered when the model is applied to ggr;hyphen;irradiated aqueous solutions.
