Provide the balanced equation, standard cell potential, ΔG° and K at 298 K for the following reaction: The oxidation of chromium(II) ion in an acidic solution to chromium(III) ion by hypochlorous acid.
Cr3+(aq) + e− → Cr2+(aq) E°red = —0.50 V
2 HClO(aq) + 2 H+(aq) + 2 e− → Cl2(g) + 2 H2O(l) E°red = 1.61 V
