Vedclass · Answer

(A) For the reaction $PbO_2 + Pb \longrightarrow 2 PbO,$ the value of $\Delta_{r} G^{\circ} For the reaction $SnO_2 + Sn \longrightarrow 2 SnO,$ the value of $\Delta_{r} G^{\circ} > 0$ indicates that the reaction is non-spontaneous,meaning $SnO_2$ (where $Sn$ is in $+4$ state) is more stable than $SnO$ (where $Sn$ is in $+2$ state). Thus,$+4$ is the more stable and characteristic oxidation state for tin.Therefore,the characteristic oxidation states are $+2$ for lead and $+4$ for tin.

In view of the signs of $\Delta_{r} G^{\circ}$ for the following reactions:
$PbO_2 + Pb \longrightarrow 2 PbO, \Delta_{r} G^{\circ} < 0$
$SnO_2 + Sn \longrightarrow 2 SnO, \Delta_{r} G^{\circ} > 0$
Which oxidation states are more characteristic for lead and tin?
