An electrochemical cell is composed of two half cells with the following half reactions: Cu2+ = 2e- Cu Pb2+ + 2e- Pb The reduction has a reduction potential of +0.34V and the oxidation has a reduction potential of -0.16V. The corresponding redox reaction involves the transfer of 2 electrons. What is the thermodynamic driving force ΔG of the overall redox reaction in this electrochemical cell?
