  • question_answer
    In which of the following system, doubling the volume of the container cause a shift to the right               [AIIMS 1996]

    A)                 \[{{H}_{2}}(g)+C{{l}_{2}}(g)=2HCl(g)\]

    B)                 \[2CO(g)+{{O}_{2}}(g)=2C{{O}_{2}}(g)\]

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

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

    Correct Answer: D

    Solution :

              Increase in volume, i.e., decrease in pressure shifts the equilibrium in the direction in which number of moles increases (Dn positive)
