What is the free energy change, ΔG\Delta \mathrm{G}, when 1.0 mole of water at 100∘C100^{{}^{\circ}} \mathrm{C} and 1 atm pressure is converted into steam at 100∘C100^{{}^{\circ}} \mathrm{C} and 1atm1 \mathrm{ atm}. pressure?

Options

  1. A540cal540 \mathrm{cal}
  2. B-9800 cal
  3. C9800cal9800 \mathrm{cal}
  4. D0cal0 \mathrm{cal}

Correct answer

D. 0cal0 \mathrm{cal}

Step-by-step solution

Condition of equilibrium, hence ΔG=0\Delta \mathrm{G}=0.
