    The equilibrium that is not affected by the increase in pressure is:

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

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

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

    D) \[{{N}_{2}}(g)+{{O}_{2}}(g)2NO(g)\]

    E) \[2N{{O}_{3}}(g)+{{O}_{2}}(g)2N{{O}_{2}}(g)\]

    Correct Answer: D

    Solution :

    If the volume of LHS and RHS in an equilibrium reaction is equal, that equilibrium is not affected by increase of pressure e.g., in the equation (d). Total number of reactants = total number of         Products Hence, \[{{N}_{2}}(g)+{{O}_{3}}(g)2NO(g)\] equation will not be affected by the increase of pressure.
