    Which of the following is correct in the reaction?                                   \[{{H}_{2}}(g)+{{I}_{2}}(g)\xrightarrow{{}}2HI(g)\]

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

    B)        \[{{K}_{p}}>{{K}_{c}}\]  

    C)        \[{{K}_{p}}<{{K}_{c}}\]  

    D)        None of these

    Correct Answer: A

    Solution :

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