Vedclass · Answer

(C) The stability of oxidation states in Group $14$ elements is governed by the inert pair effect.For $Pb$, the $+2$ oxidation state is more stable than the $+4$ state due to the inert pair effect. Thus, the reaction $PbO_{2} + Pb \rightarrow 2PbO$ is spontaneous, meaning $\Delta_{r}G^{\circ}(1) For $Sn$, the $+4$ oxidation state is more stable than the $+2$ state. Thus, the reaction $SnO_{2} + Sn \rightarrow 2SnO$ is non-spontaneous, meaning $\Delta_{r}G^{\circ}(2) > 0$.Therefore, the correct set is $\Delta_{r}G^{\circ}(1)  0$.

It is observed that $Pb^{2+}$ is more stable than $Pb^{4+}$, while $Sn^{2+}$ is less stable than $Sn^{4+}$. Consider the following reactions:
$PbO_{2} + Pb \rightarrow 2PbO; \Delta_{r}G^{\circ} (1)$
$SnO_{2} + Sn \rightarrow 2SnO; \Delta_{r}G^{\circ} (2)$
Identify the correct set from the following.
