    The ratio\[\frac{{{K}_{p}}}{{{K}_{c}}}\] for the reaction \[CO(g)+\frac{1}{2}{{O}_{2}}(g)\rightleftharpoons C{{O}_{2}}(g)\]is:

    A) \[\frac{1}{\sqrt{RT}}\]               

    B) \[{{(RT)}^{1/2}}\]

    C) RT                               

    D) 1

    Correct Answer: A

    Solution :

    [a] \[{{K}_{p}}={{K}_{C}}{{(RT)}^{\Delta n}};\] For the reaction \[CO(g)+\frac{1}{2}{{O}_{2}}(g)\rightleftharpoons C{{O}_{2}}(g)\] \[\Delta {{n}_{g}}=1-\left( 1+\frac{1}{2} \right)=-\frac{1}{2}\] \[\therefore {{K}_{p}}=\frac{{{K}_{C}}}{\sqrt{RT}};\,\frac{{{K}_{p}}}{{{K}_{C}}}=\frac{1}{\sqrt{RT}}\]
