Consider the reduction of hydroxyl radical, OH, according to the reaction H3O+ + OH + e- 2 H2O for which E0 = +2.72 V at pH 0. (a) What E0 value is expected at neutral pH 7? (b) Now compare this to the much less favorable direct reduction of hydronium, H3O+. H3O+ + e- H + H2O for which E0 = -2.10 V at pH 0. By comparing these reactions, estimate the Gibbs free energy of bond formation for HO-H, Delta GHO-H.
