    For the reaction, \[CO(g)+C{{l}_{2}}(g)COC{{l}_{2}}(g),\]the\[{{K}_{p}}/{{K}_{c}}\]is equal to

    A) \[1/RT\]           

    B)       RT                          

    C) \[\sqrt{RT}\]             

    D)        1.0

    Correct Answer: A

    Solution :

    \[{{K}_{p}}={{K}_{c}}{{(RT)}^{\Delta n}}\] \[\Delta n=\]Sum of coefficients of gaseous products sum of coefficients of gaseous reactants. \[CO(g)+C{{l}_{2}}(g)\xrightarrow{{}}COC{{l}_{2}}(g)\] \[\therefore \]\[\Delta n=1-2=-1\] \[\therefore \]\[{{K}_{p}}={{K}_{c}}{{(RT)}^{-1}}\] \[\therefore \]\[\frac{{{K}_{p}}}{{{K}_{c}}}={{(RT)}^{-1}}=\frac{1}{(RT)}\]
