    Which of the following equilibrium does not affect from change in pressure?

    A)  \[2N{{O}_{2}}(g){{N}_{2}}{{O}_{4}}(g)\]

    B)  \[2HI(g){{H}_{2}}(g)+{{I}_{2}}(g)\]

    C)  \[2{{O}_{3}}(g)3{{O}_{2}}(g)\]

    D)  \[PC{{l}_{5}}(g)PC{{l}_{3}}(g)+C{{l}_{2}}(g)\]

    Correct Answer: B

    Solution :

     \[2HI(g){{H}_{2}}(g)+{{I}_{2}}(g)\] At equilibrium, number of moles of reactant and products are same ie,\[\Delta n=0,\]Hence, in this reaction change in pressure does not affect the equilibrium.
