  • question_answer
    In which of the following reaction \[{{K}_{p}}>{{K}_{c}}\]              [AFMC 1995]

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

    B)                 \[{{H}_{2}}+{{I}_{2}}\] ⇌\[2HI\]

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

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

    Correct Answer: D

    Solution :

           For reaction \[2S{{O}_{3}}\]⇌\[{{O}_{2}}+2S{{O}_{2}}\]            \[\Delta n\] is + ve so \[{{K}_{p}}\]is more than \[{{K}_{c}}\].                                 By\[{{K}_{p}}={{K}_{c}}{{(RT)}^{\Delta n}}\]
