Question

For the cell,
$\ominus\text{Zn}_{(s)} | \text{Zn}^{+2}(1\text{M}) || \text{Ag}^{+1}(1\text{M}) | \text{Ag}_{(s)}^\oplus$
If concentration of $\text{Zn}^{+2}$ decreases to $0.1\text{ M}$ at $298\text{ K}$, then emf of cell}

• A. increase by $0.0592\text{ V}$
• B. decrease by $0.0592\text{ V}$
• C. increase by $0.0296\text{ V}$
• D. decrease by $0.0296\text{ V}$

Hint:

Decreasing product concentration shifts equilibrium forward, increasing cell potential.

Answer 1
