  • question_answer
    What is the free energy change \[\Delta G\] when \[1.0\,mole\] of water at \[{{100}^{o}}C\] and \[1\,atm\] pressure is converted into steam at \[{{100}^{o}}C\] and \[1\,atm\] pressure        [MP PET/PMT 1998]

    A)                 \[540\,cal\]        

    B)                 \[-9800\,cal\]

    C)                 \[9800\,cal\]      

    D)                 \[0\,cal\]

    Correct Answer: D

    Solution :

              At equilibrium \[\Delta G=0\].
