Fig. 3. Dependences of the initial reaction rates on (a) pH of the solution, (b) the reaction temperature, (c) the concentration of I, (d) the concentration of IIox, and (e) the concentration of hydrogen gas. (f) Arrhenius plots for I-catalyzed reduction of IIox. The observed rate constants (kobs) were determined from the initial part of the reaction. Line fit: ln kobs = 21.84−6159.3/T.
