Short Answer TypeA cell is represented by Zn|Zn2+ (aq) || Cu2+ (aq)| Cu. Given, Cu2+ + 2e- → Zn, E° = -0.763 V. Write the cell reactions, emf of the cell and state whether the cell reaction will be spontaneous or not?
The given cell is
Zn | Zn2+ (aq) || Cu2+ (aq) | Cu
Half- cell reaction at anode
Zn → Zn2+ + 2e- (oxidation)
Half-cell reaction at cathode
Cu2+ + 2e- → Cu (reduction)
Overall reaction, Zn + Cu2+ Zn2+ + Cu
E = ER° - EL°
= E - E
= 0.35 - (-0.763)
E = 1.113 V
