Draw and label a cell consisting of Bi(s), Bi(NO3)3 (aq), V(s), VCl2 (aq), salt bridge, and a wire where the Bi side undergoes reduction and the V side undergoes oxidation. Write the half reactions, balanced cell reaction where V is the reduced species and calculate the cell potential, DG (delta G), and K at 25 degrees Celsius. Is this reaction spontaneous?
E (Bi3+/Bi) = +0.327 V
E (V2+/V) = - 1.130 V
