Question Description

Use these half-cell potentials:

Cr2O72- (aq) + 14 H+ + 6e- → 2 Cr3+ (aq) + 7 H2O (l) ξo=1.36

Cl2 (g) + 2e- → 2 Cl- ξo=1.33

Calculate ∆Go for the voltaic cell shown above.

n= moles of electrons transferred
F= 96500 Coulomb (charge on one mol of electrons)
Use the units kJ in your answer. 

ΔGo =- n F ξo.
