`S (rhombic) + O_(2)(g) rightarrow SO_(2)(g), Delta H = -297.5 kJ`
`S(monoclinic) + O_(2) (g) rightarrow SO_(2)(g), Delta H = -300 kJ`
The above data can predict that

A

Rhomic sulphure is yellow is colour

B

monoclinic sulphur is more stalbe

C

monoclinic sulphur is more stable

D

The process `S(` rhombic `) rarr S(` monoclinic ``)` is endothermic

Text Solution

Verified by Experts

The correct Answer is:
4
`{:(S(r),+,O_(2),rarr,SO_(2),,-297.5kJ),(SO_(2),rarr ,S(m),+,O_(2),,+300kJ):}`
`bar(S(r)rarr S(m)" "+2.5kJ ` )so process is endothermic
