Solution

The correct option is D 2
Cell reaction
$M^{4 +} + H_{2} \to M^{2 +} + 2 H^{\oplus} E_{c e l l} = E_{c e l l}^{\circ} - \frac{0.06}{2} l o g \frac{[M^{2 +}]}{[M^{4 +}]} 0.092 = 0.151 - 0.03 l o g \frac{M^{2 +}}{M^{4 +}} = - 0.06 = - 0.03 l o g_{10} \frac{[M^{+ 2}]}{[M^{+ 4}]} \frac{[M^{2 +}]}{[M^{4 +}]} = 10^{2} [G i v e n \frac{M^{2 +} (a q)}{[M^{4 +} (a q)]}] 10^{x} = 10^{2} = x = 2$
