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

    A)  \[{{K}_{p}}={{K}_{c}}\]

    B)  \[{{K}_{p}}>{{K}_{c}}\]

    C)  \[{{K}_{p}}<{{K}_{c}}\]

    D)  \[{{K}_{p}}\ge {{K}_{c}}\]

    Correct Answer: A

    Solution :

     For equation\[{{H}_{2}}(g)+{{I}_{2}}(g)\xrightarrow[{}]{{}}2HI,\]the value of \[\Delta n=2-(1+1)=0\] Hence, By using formulae \[{{K}_{p}}={{K}_{c}}{{(RT)}^{\Delta n}}\] \[{{K}_{p}}={{K}_{c}}{{(RT)}^{0}}\] \[{{K}_{p}}={{K}_{c}}\]
