    For which of the following reactions,\[{{K}_{p}}={{K}_{c}}?\]

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

    B)  \[{{N}_{2}}+{{O}_{2}}2NO\]

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

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

    Correct Answer: B

    Solution :

     \[{{K}_{p}}={{K}_{c}}{{(RT)}^{\Delta n}}\] For the reaction: \[{{N}_{2}}+{{O}_{2}}2NO\] \[\Delta n=2-2=0\] \[\therefore \] \[{{K}_{p}}={{K}_{c}}{{(RT)}^{0}}\] \[{{K}_{p}}={{K}_{c}}\]
