  • question_answer
    Change in volume of the system does not alter the number of moles in which of the following equilibrium [AIEEE 2002]

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

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

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

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

    Correct Answer: A

    Solution :

              \[{{N}_{2(g)}}+{{O}_{2(g)}}\]⇌\[2N{{O}_{(g)}}\];            \[\Delta n=2-2=0\]
