At $ 298 K : \Delta_{ f } H ^{\circ}\left( SnO _2( s )\right)=-581.0 kJ mol ^{-1}, \Delta_{ fH } H ^{\circ}\left( CO _2( g )\right)=-394.0 kJ mol ^{-1}$
$S ^{\circ}\left( SnO _2( s )\right)=56.0 J K ^{-1} mol ^{-1}, S ^{\circ}( Sn ( s ))=52.0 J K ^{-1} mol ^{-1}$
$S ^{\circ}( C ( s ))=6.0 J K ^{-1} mol ^{-1}, S ^{\circ}\left( CO _2( g )\right)=210.0 J K ^{-1} mol ^{-1}$
Assume that the enthalpies and the entropies are temperature independent.
The order of the energies would be :
