S("rhombic")+O(2)(g)toSO(2)(g), DeltaH =...

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

A

rhombic sulphur is yellow in color

B

monoclinic sulphur has metallic lustre

C

monoclinic sulphur is more stable

D

`DeltaH_("translition")of S_(R) of S_(M)` is endothermic

Text Solution

Verified by Experts

The correct Answer is:
d

subtracting second equation from first , we get `S_((R))toS_((M))DeltaH=+2.5kJ`, endothermic
