    For the following reaction in gaseous phase\[CO+\frac{1}{2}{{O}_{2}}\to C{{O}_{2}}\]; \[{{K}_{p}}/{{K}_{c}}\] is                  [DCE 2002]

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

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

    C)                 \[(RT)\]               

    D)                 \[{{(RT)}^{-1}}\]

    Correct Answer: B

    Solution :

               \[{{K}_{p}}={{K}_{c}}{{[RT]}^{\Delta {{n}_{g}}}}\]                    \[\Delta {{n}_{g}}=1-1.5=-0.5\]                                 \[{{K}_{p}}={{K}_{c}}{{[RT]}^{-1/2}}\]   \[\therefore \,\,\frac{{{K}_{p}}}{{{K}_{c}}}={{[RT]}^{-1/2}}\]
