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

    A)  \[1\]                                    

    B)  \[RT\]

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

    D)  \[{{(RT)}^{1/2}}\]

    Correct Answer: C

    Solution :

    \[CO(g)+\frac{1}{2}{{O}_{2}}(g)\rightleftharpoons C{{O}_{2}}(g),\] \[\Delta n=1-1.5\] \[\Delta n=-0.5\] \[{{K}_{p}}={{K}_{c}}{{(RT)}^{\Delta n}}\] \[\frac{{{K}_{p}}}{{{K}_{c}}}={{(RT)}^{\Delta n}}\] \[\frac{{{K}_{p}}}{{{K}_{c}}}={{(RT)}^{-0.5}}\]                 or                            \[\frac{{{K}_{p}}}{{{K}_{c}}}=\frac{1}{\sqrt{RT}}\]
