  • question_answer
    In which of the following case Kp is less than Kc [AFMC 1997; Pb. PMT 2000]

    A)                 \[{{H}_{2}}+C{{l}_{2}}\]⇌\[2HCl\]       

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

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

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

    Correct Answer: B

    Solution :

             \[\underset{3}{\mathop{2S{{O}_{2}}}}\,+{{O}_{2}}\]⇌ \[\underset{2}{\mathop{2S{{O}_{3}}}}\,\] for this reaction                                 \[\Delta n\]= ?1  ; \\[{{K}_{c}}>{{K}_{p}}\]
