For which of the following processes is `DeltaS` negative?

A

`H_(2)(g) rarr 2H(g)`

B

`N_(2)(g,1atm) rarr N_(2)(g,5atm)`,

C

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

D

`C("diamond") rarr C("graphite")`

Text Solution

Verified by Experts

At higher pressure, `N_(2)(g)` will have less entropy
`:. DeltaS` will be -ve.
