A voltaic cell consists of a Pb/Pb2+ half cell and a Cu/Cu2+ half cell at 25C. The initial concentrations of Pb2+ and Cu2+ are 5.10x10^-2M and 1.40M, respectively.
1. What is the cell potential when the concentration of Cu2+ has fallen to 0.250M?
2. What are the concentrations of Pb2+ and Cu2+ when the cell potential falls to 0.370V?
