We’re being asked to rank the given species from strongest to weakest reducing agents. Reducing agent is the species that are being oxidized in a redox reaction. Recall the mnemonics LEO GER.
Loss Electrons → Oxidation → Reducing Agent
Gain Electrons → Reduction → Oxidizing Agent
The strongest reducing agent would be the element that would be easily oxidized or easily loses an electron:
• it will be the species moving away from the electrons
• it will be the anode which means it will have the smallest E°
Rank form strongest to weakest the following reducing agents: F -, Pb, Ag, I-
1) F-, Pb, Ag, l-
2) Pb, l-, Ag, F-
3) Pb, F-, Ag, l-
4) Pb, I-, F-, Ag
