Consider the reactions:(P)S ("rhombic") +(3)/(2)O_(2)(g) to SO_(3)(g), ""DeltaH_(1)(Q) S("Monoclinic")0 +(3)/(2)O_(2)(g) to SO_(2)""DeltaH_(2)(R) S("rhiombic")+O_(3)(g) to SO_(3)(g)""DeltaH_(3) (S)S("monoclince")+O_(3)(g) to SO_(3)(g)""DeltaH_(4)

Answer»

`DeltaH_(1)ltDeltaH_(2)LT DeltaH_(4)`(magnitude only)
`DeltaH_(1)ltDeltaH_(3)lt DeltaH_(4)`(magnitude only)
`DeltaH_(1)ltDeltaH_(2)=DeltaH_(3)lt DeltaH_(4)`(magnitude only)
`DeltaH_(1) + DeltaH_(4)=DeltaH_(2)lt DeltaH_(3)`

Answer :a,B,d
