For the equilibrium H ₂ O _ (l) H ₂ O _ ( g ) at 1 atm and 298 ~K ,

Options

  1. Astandard free energy change is equal to zero ( G^ =0 )
  2. Bfree energy change is less than zero ( G < 0)
  3. Cstandard free energy change is less than zero ( G^ < 0 )
  4. Dstandard free energy change is greater than zero ( G^ >0 ) .

Correct answer

A. standard free energy change is equal to zero ( G^ =0 )

Step-by-step solution

H ₂ O _ (l) H ₂ O _ (g) This is a spontaneous process at standard conditions thus, the standard free energy change must be less then zero, i.e. G^ < 0 .
