  • question_answer
    The equilibrium concentration of \[X,\,Y\] and \[Y{{X}_{2}}\] are 4, 2 and 2 moles respectively for the equilibrium \[2X+Y\]⇌\[Y{{X}_{2}}\]. The value of \[{{K}_{c}}\] is [EAMCET 1990]

    A)                 0.625    

    B)                 0.0625

    C)                 6.25       

    D)                 0.00625

    Correct Answer: B

    Solution :

              \[{{K}_{c}}=\frac{[Y{{X}_{2}}]}{{{[X]}^{2}}[Y]}=\frac{2}{4\times 4\times 2}=\frac{1}{16}=0.0625\].
