Equilibrium constants and rate constants involving Cl"~aq!, Cl, Cl2 "(aq), HO", H2O, and H2O2(aq) determined at 29762 K in the aqueous phase are updated and evaluated. Most of the rate constants and equilibrium constants are obtained by either pulse radiolysis or laser flash photolysis. The recommended values of rate constants and equilibrium constants are achieved by un-weighted averaging of t...
