For the process H (2) O (l) ⇔H (2) O (g)...

For the process `H _(2) O (l) ⇔H _(2) O (g)` at `T = 100 ^(@)C` and 1 atmosphere pressure, the correct choice is

A

`Delta S _("system") gt 0 and Delta S _("surroundings") gt 0`

B

`Delta S _("system") gt 0 and Delta S _("surroundings") lt 0`

C

`Delta S _("system") lt 0 and Delta S _("surroundings") gt 0`

D

`Delta S _("system") lt 0 and Delta S _("surroundings") lt 0`

Text Solution

Verified by Experts

`DeltaS _("total") = DeltaS_("system")+ Delta S_("surroundings")`
`Delta S _("surrounding")= (Delta H _("system"))/(T), Delta H _("system") ` is positive
