A. Sn | Sn 2+ (1M) || Pb 2+ (1M) |Pb
B. Zn | Zn 2+ (1M) || Sn 2+ (1M) | Sn

1. identify anode and cathode
2. calculate the standard cell potential (is the cell reaction spontaneous?)
3. write the equation for the cell reaction which species is oxidized, reduced? Which species is the oxidizing agent and which one is the reducing agent? How many electrons are transferred?
4. calculate the standard free energy change for the cell reaction
5. calculate the equilibrium constant K for the cell reaction
