    In which of the following equilibria, the value of \[{{K}_{p}}\] is less than \[{{K}_{c}}\].

    A) \[{{H}_{2}}+{{I}_{2}}\rightleftharpoons 2HI\]

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

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

    D) \[CO+{{H}_{2}}O\rightleftharpoons C{{O}_{2}}+{{H}_{2}}\]

    Correct Answer: B

    Solution :

    \[{{K}_{p}}=\,\,{{K}_{c}}{{\left( RT \right)}^{\Delta n}}\]; When\[\operatorname{M}= 2 - \left( 2 + 1 \right) = -1\], i.e., negative, \[{{K}_{p}}<{{K}_{c}}\].
