Determine the cell diagram for the reaction below. Assume a platinum electrode is used when no other solid is present.
2Fe2+(aq) + Pb2+(aq) → 2Fe3+(aq) + Pb(s)
◦ Pt(s) | Fe2+(aq), Fe3+(aq) || Pb2+(aq) | Pb(s)
◦ Pb(s) | Pb2+(aq) || Fe2+(aq), Fe3+(aq) | Pt(s)
◦ Pt(s) | Fe3+(aq), Fe2+(aq) || Pb(s) | Pb2+(aq) | Pt(s)
◦ Pt(s) | Pb2+(aq) | Pb(s) || Fe2+(aq), Fe3+(aq) | Pt(s)
◦ Pt(s) | Fe2+(aq), Pb2+(aq) || Fe3+(aq) | Pb(s)
