Problem

It is noted that Pb2+\text{Pb}^{2+} is more stable than Pb4+\text{Pb}^{4+}, but Sn2+\text{Sn}^{2+} is less stable than Sn4+\text{Sn}^{4+}, in the reactions PbO2+Pb→2PbO; ΔrG∘(1)\text{PbO}_2+\text{Pb}\rightarrow2\text{PbO};\ \Delta_rG^\circ(1) SnO2+Sn→2SnO; ΔrG∘(2)\text{SnO}_2+\text{Sn}\rightarrow2\text{SnO};\ \Delta_rG^\circ(2) Choose the correct statement.
