Consider the following galvanic cell at 25oC: Pt | Cr2+ (0.30 M), Cr3+(2.0 M) | | Co2+(0.20

Question:

Consider the following galvanic cell at 25oC:
Pt | Cr2+ (0.30 M), Cr3+(2.0 M) | | Co2+(0.20 M) | Co The overall reaction and equilibrium constant value are
2Cr2+(aq) + Co2+(aq) → 2Cr3+(aq) + Co(s) K = 2.79 × 107
Calculate the cell potential ϐ for this galvanic cell and ΔG for the cell reaction at these conditions.
