Consider the following reaction at equilibrium
$2 F e^{2 +} (a q) + C u^{2 +} \to 2 F e^{3 +} (a q) + C u$
When the reaction comes to equilibrium, what is the cell voltage?

Options:

Answer:

Solution:

When the equilibrium is attained in cell reaction, the cell will no longer do any electrical work, i.e., $Δ G = 0$
$- Δ G = n E_{c e l l} F$
So $0 = n E_{c e l l} F$
or $E_{c e l l} = 0$ .
