Final answer:
Zinc, being higher on the activity series, will spontaneously oxidize lead (Pb), in which zinc acts as a reducing agent. Option b
Step-by-step explanation:
Based on the given electrochemical (E°) values and considering the activity series, zinc will oxidize lead (Pb). This is because zinc is higher in the activity series and more easily oxidized than lead.
The reaction would be spontaneous and zinc would serve as a reducing agent, losing electrons in the process, whereas lead would be oxidized. Therefore, the correct answer to the question is that Zinc will (b) oxidize Pb.
