Question

For a $M g ∣ M g^{2 +} (a q) ∥ A g^{+} (a q) ∣ A g$ the correct Nernst Equation is: [2025]

Cell reaction: $Mg (s) + 2 {Ag}^{+} (a q) \to {Mg}^{2 +} (a q) + 2 Ag (s)$

Nernst equation: $E_{cell} = E_{cell}^{\circ} - \frac{R T}{n F} \ln Q$

$E_{cell} = E_{cell}^{\circ} - \frac{R T}{2 F} \ln \frac{[{Mg}^{2 +}]}{{[{Ag}^{+}]}^{2}}$

$E_{cell} = E_{cell}^{\circ} + \frac{R T}{2 F} \ln \frac{{[{Ag}^{+}]}^{2}}{[{Mg}^{2 +}]}$
