 Consider an electrochemical cell constructed from the following half cells, linked by an external circuit and by a KCl salt bridge.  

• an Al(s) electrode in 1.0 M Al(NO3)3 solution        

 • a Pb(s) electrode in 1.0 M Pb(NO3)2 solution

a) write the balanced overall cell reaction that will make the cell spontaneous. Keep in mind that aluminum will transfer 3 electrons per aluminum atom while lead will only transfer 2.

b) calculate E cell

c) how many electrons will be transferred in the balanced overall reaction?
