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 Cr2O72- + 34 H3O+ →6 IO3- + 10 Cr3+ + 51 H2O

E°IO3-/I2, H3O+ = +1.195, E°Cr2O72-/Cr3+, H3O+ = +1.232
