Which of the following reactions will have the value of `DeltaS` with a negative sign?

A

`H_(2)O_((l))rarrH_(2)O_((g))`

B

`2SO_(2(g))+O_(2(g))rarr2SO_(3(g))`

C

`Cl_(2(g))rarr2Cl_((g))`

D

`CaCO_(3(s))rarr CaO_((s))+CO_(2(g))`

Text Solution

Verified by Experts

The correct Answer is:
B
`2SO_(2(g))+O_(2(g)) rarr 2SO_(3(g))`
`Deltan_(g)=2-3=-1, DeltaS=-ve`
