  • question_answer
    For the reaction\[{{H}_{2}}+{{I}_{2}}=2HI\],the equilibrium concentration of \[{{H}_{2\,}},\,{{I}_{2}}\] and \[HI\] are 8.0, 3.0 and 28.0 mol per litre respectively, the equilibrium constant of the reaction is [BHU 2000; CBSE PMT 2001]

    A)                 30.66    

    B)                         32.66

    C)                 34.66    

    D)                 36.66

    Correct Answer: B

    Solution :

              \[{{K}_{c}}=\frac{{{[HI]}^{2}}}{[{{H}_{2}}]\,\,[{{I}_{2}}]}=\frac{{{(28)}^{2}}}{8\times 3}=32.66\]
