A) Calculate E° for the reaction:

2 MnO₄^- + 10 Cl^- + 16 H₃O⁺ →2 Mn²⁺ + 5 Cl₂ + 24 H₂O

E°_{MnO₄^-/Mn²⁺,
H₃O⁺} = +1.507, E°_Cl₂/Cl^- = +1.358

Round your answer to 3 significant figures.

-------------------------------------------------------------------------------------

B) Use standard reduction potentials to calculate ΔG° for the reaction:

3 I₂ + 5 Cr₂O₇^2- + 34 H₃O⁺ →6 IO₃^- + 10 Cr³⁺ + 51 H₂O

E°_{IO₃^-/I₂,
H₃O⁺} = +1.195, E°_{Cr₂O₇^2-/Cr³⁺,
H₃O⁺} = +1.232
