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

    A)  1             

    B)  \[\frac{1}{4}\]

    C)  \[\frac{1}{\sqrt{RT}}\]

    D)  \[{{[RT]}^{1/2}}\]

    Correct Answer: C

    Solution :

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