    Which of the following equilibria will shift to right side on increasing the temperature     [MP PMT 2000]

    A)                 \[C{{O}_{(g)}}+{{H}_{2}}{{O}_{(g)}}\]⇌\[C{{O}_{2}}_{(g)}+{{H}_{2}}_{(g)}\]

    B)                 \[2S{{O}_{2}}_{(g)}+{{O}_{2}}_{(g)}\]⇌\[2S{{O}_{3}}_{(g)}\]

    C)                 \[{{H}_{2}}{{O}_{(g)}}\]⇌\[{{H}_{2}}_{(g)}+\frac{1}{2}{{({{O}_{2}})}_{(g)}}\]

    D)                 \[4HC{{l}_{(g)}}+{{O}_{2}}_{(g)}\]⇌\[2{{H}_{2}}{{O}_{(g)}}+2C{{l}_{2}}_{(g)}\]

    Correct Answer: C

    Solution :

             \[{{H}_{2}}O(g)\]⇌ \[{{H}_{2(g)}}+\frac{1}{2}{{O}_{2(g)}}\]                                 In this reaction volume is increasing in the forward reaction. So on increasing temperature reaction will proceed in forward direction.
