JEE Main & Advanced Chemistry Equilibrium / साम्यावस्था Sample Paper Topic Test - Chemical Equilibrium

  • question_answer
    For the reaction \[A+BC+D,\]equilibrium  concentration of [C] =[D] = 0.5M if we start with 1 mole each of A and B. Percentage of A converted into C if we start with 2 moles of A and 1 mole of B, is

    A) 25%

    B) 40%

    C) 66.66%

    D) 33.33%

    Correct Answer: D

    Solution :

    [d] \[A+BC+D\]
    \[\left. \begin{matrix}    1 & 1 & 0 & 0  \\    (1-x) & (1-x) & x & 0  \\ \end{matrix} \right]\text{Set}\,\text{I}\]\[\left. \begin{matrix}    2 & 1 & 0 & 0  \\    (2-y) & (1-y) & y & y  \\ \end{matrix} \right]\text{Set}\,\text{II}\]
    \[{{K}_{c}}=\frac{{{x}^{2}}}{{{(1-x)}^{2}}}=\frac{{{y}^{2}}}{(2-y)(1-y)}=1\]since x = 0.5
    \[\therefore \]      \[y=\frac{2}{3}\]
    Fraction of A converted into products
