    \[{{\operatorname{K}}_{p}}/{{K}_{c}}\]for the reaction: \[\operatorname{CO}\left( g \right)+{{O}_{2}}\left( g \right)\rightleftharpoons C{{O}_{2}}\left( g \right)\]is:

    A) 1      

    B)               RT   

    C) \[1\sqrt{RT}\]                

    D) \[{{\left( RT \right)}^{{}^{1}/{}_{2}}}\]

    Correct Answer: C

    Solution :

    \[1/\sqrt{RT}\] For reaction \[\operatorname{CO}\left( g \right)+{}^{1}/{}_{2}{{O}_{2}}\left( g \right)\rightleftharpoons C{{O}_{2}}\left( g \right)\] \[\Delta {{n}_{g}}={{n}_{p}}-{{n}_{r}}\] \[=1-\left( 1+\frac{1}{2} \right)=-\frac{1}{2}\]  \[\frac{{{k}_{p}}}{{{k}_{e}}}={{\left( RT \right)}^{\Delta \operatorname{n}}}\] \[{{\left( RT \right)}^{-\frac{1}{2}}}\] \[\frac{{{k}_{p}}}{{{k}_{e}}}=\frac{1}{\sqrt{\operatorname{RT}}}\]
