    In the equilibrium reaction \[2HI(g)\rightleftharpoons {{H}_{2}}+{{I}_{2}}\]which of the following expressions is true?

    A)  \[{{K}_{p}}={{K}_{c}}\]         

    B)  \[{{K}_{c}}=2{{K}_{p}}\]

    C)  \[{{K}_{p}}>{{K}_{c}}\]  

    D)  \[{{K}_{c}}={{K}_{p}}{{(RT)}^{2}}\]

    Correct Answer: A

    Solution :

    \[2HI(g){{H}_{2}}+{{I}_{2}}\] \[\Delta n=2-2=0\] \[\because \]     \[{{K}_{p}}={{K}_{c}}{{(RT)}^{\Delta n}}\] \[\Rightarrow \]               \[{{K}_{p}}={{K}_{c}}{{(RT)}^{0}}\] \[\therefore \]  \[{{K}_{p}}={{K}_{c}}\]
