For the equilibrium `H_(2)O(l) iff H_(2)O(g)` at 1 atm and 298 K

A

Standard free energy change is equal to zero `(DeltaG^(@)=0)`

B

Free energy change is less than zero `(DeltaG lt 0)`

C

Standard free energy change is less than zero `(DeltaG^(@)lt0)`

D

Standard free energy change is greater than zero `(DeltaG^(@)gt0)`

Text Solution

Verified by Experts

The correct Answer is:
C
For reaction `H_(2)O(l)rarrH_(2)O(g)`
`Deltan=1` means positive.
