The standard reduction potentials Eº for the half reactions are as
Zn \(\text { → }\) Zn2+ + 2e– ; Eº = 0.76V
Fe \(\text { → }\) Fe2+ + 2e– ; Eº = 0.41V
The EMF for the cell reaction will be
Zn \(\text { → }\) Zn2+ + 2e– ; Eº = 0.76V
Fe \(\text { → }\) Fe2+ + 2e– ; Eº = 0.41V
The EMF for the cell reaction will be
- – 0.3V
- 0.35V
- 1.17V
- –1.17V
Answer
(B) 0.35V
