    Which of the following relationship is correct for reversible reaction, \[{{H}_{2}}+{{I}_{2}}2HI\]?

    A)  \[{{K}_{p}}<1\]

    B)  \[{{K}_{p}}={{K}_{c}}\]

    C)  \[{{K}_{p}}>1\]   

    D)  None of these

    Correct Answer: B

    Solution :

     \[{{H}_{2}}+{{I}_{2}}2HI\] \[\Delta n={{n}_{p}}-{{n}_{r}}\] \[=2-2=0\] \[{{K}_{p}}={{K}_{c}}{{(RT)}^{\Delta n}}\] \[{{K}_{p}}={{K}_{c}}{{(RT)}^{o}}\] Hence,  \[{{K}_{p}}={{K}_{c}}\]
