Please help me with this. Thanks.

Consider an electrochemical cell constructed from the following half cells, linked by an external
circuit and by a KCI salt bridge.
• an Al(s) electrode in 1.0 M AI(NO3)3 solution
• a Pb(s) electrode in 1.0 M Pb(NO3)2 solution
The balanced overall (net) cell reaction is
O Pb2*(aq) + Al(s) Pb(s) + AI3*(aq)
O 3Pb(s) + 2AI3+(aq) 3Pb2+(aq) + 2Al(s)
O Pb(s) + Al3+(aq) Pb2+(aq) + Al(s)
O 3PB2+(aq) + 2AI(s) 3Pb(s) + 2AI3*(aq)
