S_("rhombic")+O_(2)(g)toSO_(2)(g), DeltaH = -297 .5 kcal S_("monoclinic")+ O_(2)(g) to SO_(2)(g) , DeltaH = -300 kJ

Answer»

rhombic sulphur is YELLOW in color
monoclinic sulphur has METALLIC lustre
monoclinic sulphur is more stable
`DeltaH_("translition")of S_(R) of S_(M)` is endothermic

Solution :SUBTRACTING SECOND equation from FIRST , we get`S_((R))toS_((M))DeltaH=+2.5kJ`, endothermic
