b) A galvanic cell consists of a Pb electrode in a 1.0MPb(NO2)2 solution and Pt electrode in a 1.0MNaCl solution, with Cl2 gas bubbled around the electrode. Appendix 1 shows the list of standard reduction potentials at 25C. i) Express the half cell and overall reactions (4 marks) ii) Predict the electrochemical forces (EMF) generated by the cell under standard conditions (2 marks)
