At 373 K, steam and water are in equilibrium and `DeltaH=40.98" kJ mol"^(-1)`. What will be `DeltaS` for conversion of water into system ?
`H_(2)O_((l))rarrH_(2)O_((g))`

A

`"109.8 J K"^(-1)"mol"^(-1)`

B

`"31 J K"^(-1)"mol"^(-1)`

C

`"21.98 J K"^(-1)"mol"^(-1)`

D

`"326 J K"^(-1)"mol"^(-1)`

Text Solution

Verified by Experts

The correct Answer is:
A
`DeltaS_("vap")=(DeltaH_("vap"))/(T_(b))=(40.98xx1000)/(373)`
`="109.8 J K"^(-1)"mol"^(-1)`
