    Which of the following is true for the reaction \[CO(g)+\frac{1}{2}{{O}_{2}}(g)C{{O}_{2}}(g)\]

    A)  \[{{K}_{p}}>{{k}_{c}}\]

    B)  \[{{K}_{p}}<{{k}_{c}}\]

    C)  \[{{K}_{p}}={{k}_{c}}\]

    D)  \[{{K}_{p}}\ge {{k}_{c}}\]

    Correct Answer: B

    Solution :

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