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