N2 - The relative rate constant for the reactions of eaq- with H+ compared to Cd2+, Zn2+, and acetone were measured as a function of concentrations up to 2 M. The results show either that keaq-+H+/keaq-+Cd 2+ and keaq-+H+/ keaq-+aoetone decrease at high concentrations or that alternatively the ratio of rates is constant but the yields of eaq- (G(eaq-)) decrease in these concentrated solutions. The results are related to the time dependence of the above-mentioned ratios of the rate constants, as postulated by Schwarz, and to the dry-electron concept proposed by Hamill. One cannot, at this stage, make a definite decision with respect to the relative importance of the two alternatives.
