Chemistry

A) Calculate E° for the reaction:

2 MnO4- + 10 Cl- + 16H3O+ →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 thereaction:

3 I2 + 5 Cr2O72- +34 H3O+ →6 IO3- + 10Cr3+ + 51 H2O

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