For the process H(2)O(l)toH(2)O(g) at t=...

For the process `H_(2)O(l)toH_(2)O(g)` at `t=100^(@)C` and 1 atmosphere pressure, the correct choice is:

A

`DeltaS_("system") gt 0, DeltaS_("surroundings")gt0`

B

`DeltaS_("system")gt0,DeltaS_("surroundings")lt0`

C

`DeltaS_("system") lt 0 and DeltaS_("surroundings") gt 0`

D

` DeltaS_("System")lt 0 and DeltaS_("surroundings")lt0`

Text Solution

Verified by Experts

The correct Answer is:
B
At equilibrium, `H_(2)O(l)hArrH_(2)O(g)` 1 atm, `100^(@)C`
`DeltaS_("Total")=0`
i.e., `DeltaS_("system")+DeltaS_("surroundings")=0`
`thereforeDeltaS_("system")gt0 and DeltaS_("surroundings") lt 0`
