    Which of the following is true for the reaction \[{{H}_{2}}O(l)\underset{{}}{\overset{{}}{\longleftrightarrow}}{{H}_{2}}O(g)\] at \[{{100}^{o}}C\] and 1 atm?

    A)  \[\Delta E=0\]

    B)  \[\Delta H=0\]

    C)  \[\Delta H=\Delta E\]

    D)  \[\Delta H=T.\Delta S\]

    Correct Answer: D

    Solution :

                    At equilibrium \[\Delta G=0\] Hence,                  \[0=\Delta H-T.\Delta S\] or                            \[\Delta H=T.\Delta S\]
