question

A voltaic cell is made up of a silver electrode in a 1M silver nitrate solution and an aluminum electrode in a 1M aluminum nitrate solution. The half reactions are 1) Ag^+ + e^- \rightarrow Ag (s) E° = .80 volt, and (2) Al^3+ +3e^-\rightarrow Al(s) E° = -1.66 volt, calculate the standard free energy change, ∆G°, in Kcal / mole. 1 cal = 4.184 joule 1 F = 96,500 coul, 1 Kcal = 1000 cal.
