1.

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 `(Delta G^(@) = 0)`B. free energy change is less than zero `(Delta G lt 0)`C. standard free energy change is less than zero `(Delta G^(@) lt 0)`D. standard free energy change is more than zero `(Delta G^(@) gt 0)`

Answer» Correct Answer - A
For a reversible process at at equilibrium, under standard conditions (1 atm and `298 K`), `Delta G^(@) = 0`.
