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