JEE Main & Advanced Chemistry Equilibrium / साम्यावस्था Question Bank Law of equilibrium and Equilibrium constant

  • question_answer
    In a reaction \[A+B\]⇌ \[C+D\], the concentrations of A, B, C and D (in moles/litre) are 0.5, 0.8, 0.4 and 1.0 respectively. The equilibrium constant is          [BHU 1981]

    A)                 0.1         

    B)                 1.0

    C)                 10          

    D)                 \[\infty \]

    Correct Answer: B

    Solution :

           For A + B ⇌ C + D                                 \[K=\frac{[C]\,\,[D]}{[A]\,\,[B]}=\frac{0.4\times 1}{0.5\times 0.8}=1\].
