1. Calculate the equilibrium constant, K, for the reaction in the Galvanic Pb-Cu cell. (Report your answer in scientific notation to three significant figures. Use * for the multiplication sign and ^ to designate the exponent.) Cu+ (aq) + Pb (s) → Cu (s) + Pb2+ (aq) Eocell = 0.647 V
K =
2. For the reaction Mg (s) + Ni2+ (aq) →→ Mg2+ (aq) + Ni (s), Eocell = 2.629 V.
Calculate the cell potential at T = 50.0oC when [Ni2+] = 1.25 M, [Mg2+] = 0.567 M
E cell = ___ V
