{E^0}

for the half cell

Z{n^{2 + }}/Zn

- 0.76

, e.m.f of the cell

Zn/Z{n^{2 + }}\left( {1M} \right)//2{H^ + }\left( {2M} \right)/{H_2}\left( {1\,{\text{atm}}} \right)

View answer and explanation

Correct option: B

+ 0.76V

Option B is correct. The EMF of the cell is equal to the standard reduction potential of the cathode minus the standard reduction potential of the anode. In this case, the standard hydrogen electrode (SHE) is the cathode, and the zinc electrode is the anode.
