  • question_answer In which of the following equilibrium \[{{K}_{c}}\]and \[{{K}_{p}}\]are not equal?

    A)  \[2C(s)+{{O}_{2}}(g)2C{{O}_{2}}(g)\]

    B)  \[2NO(g){{N}_{2}}(g)+{{O}_{2}}(g)\]

    C)  \[S{{O}_{2}}(g)+N{{O}_{2}}(g)S{{O}_{3}}(g)+NO(g)\]

    D)  \[{{H}_{2}}(g)+{{l}_{2}}(g)2Hl(g)\]

    Correct Answer: A

    Solution :

    \[{{K}_{p}}={{K}_{c}}{{(RT)}^{\Delta {{n}_{g}}}}\] \[\Delta {{n}_{g}}\ne 0\]for the reaction \[2C(s)+{{O}_{2}}(g)2C{{O}_{2}}\] Thus, \[{{K}_{p}}\ne {{K}_{c}}\]
