  • question_answer
    In which of the following equilibrium systems is the rate of the backward reaction favoured by increase of pressure [KCET 2001]

    A)                 \[PC{{l}_{5}}\]⇌\[PC{{l}_{3}}+C{{l}_{2}}\]     

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

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

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

    Correct Answer: A

    Solution :

             The rate of backward reaction favoured by increase of pressure in the reaction as \[\Delta n\] is positive                                 \[PC{{l}_{5}}\]⇌ \[PC{{l}_{3}}+C{{l}_{2}}\]
