For the equilibrium H(2) O (1) hArr H(...

For the equilibrium
`H_(2) O (1) hArr H_(2) O (g)`
at 1 atm `298 K`

A

Standard free energy change is equal to zero `(DeltaGlt0)`

B

standard Free energy change is equal to zero (`DeltaG^(@)=0`)

C

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

D

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

Text Solution

Verified by Experts

The correct Answer is:
B
`H_(2)O_(i)iffH_(2)O_(g)`
This is a spontaneous process at standard conditions thus,the standard free energy change must be less then zero,i.e.,`DeltaG^(@)lt0`.
