Temperature Dependence of the Branching Ratio of SO5 - Radicals Self-Reaction in Aqueous Solution

Temperature dependence of chain oxidation of bisulfite occurring through the self-reaction of peroxomonosulfate radicals, SO5 - + SO5 - ⇒ SO4 - + SO4 - + O2 (k 1a), SO5 - + SO5 - ⇒ S2O8 2- + O2 (k 1b), has been determined over the range 278−313 K. The activation energy of the branching ratio of SO5...

Description
Summary:Temperature dependence of chain oxidation of bisulfite occurring through the self-reaction of peroxomonosulfate radicals, SO5 - + SO5 - ⇒ SO4 - + SO4 - + O2 (k 1a), SO5 - + SO5 - ⇒ S2O8 2- + O2 (k 1b), has been determined over the range 278−313 K. The activation energy of the branching ratio of SO5 - self-reaction, k 1a/k 1b, was derived, E a = 7.4 ± 2.4 kcal mol-1.
