    Which one of the following has \[\Delta {{S}^{o}}\] greater than zero [AIIMS 2003]

    A)                 \[CaO+C{{O}_{2}}(g)\]⇌ \[CaC{{O}_{3}}(s)\]

    B)                 \[NaCl\,(aq)\] ⇌ \[NaCl(s)\]

    C)                 \[NaN{{O}_{3}}(s)\] ⇌ \[N{{a}^{+}}(aq)+NO_{3}^{-}(aq)\]

    D)                 \[{{N}_{2}}(g)+3{{H}_{2}}(g)\] ⇌ \[2N{{H}_{3}}(g)\]

    Correct Answer: C

    Solution :

              \[NaN{{O}_{3}}\]is a solid, which is converted to liquid ions.
