Consider the aqueous electrolysis of KBr, potassium bromide: KBr (s) –> K+ (aq) + Br- (aq)   Given the following possible oxidation and reduction reactions, determine the Eocell for the following reaction: 2 H2O (l) + 2 Br- (aq) ⇌ H2 (g) + 2 OH- (aq) + Br2 (l)   Possible Reduction Reactions: K+(aq) + e– ⇌ K(s)                                   Eo = -2.92 V 2 H2O(l) + 2 e– ⇌ H2(g) + 2 OH–(aq)    Eo = -0.83 V    Possible Oxidation Reactions: 2 Br-(aq) ⇌  Br2 (l) + 2 e–                     Eo = -1.07 V    2 H2O(l) ⇌ O2(g) + 4 H+(aq) + 4 e–     Eo = -1.23 V
