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

  • question_answer
    The equilibrium constant for the reaction:  \[{{N}_{2(g)}}+{{O}_{2(g)}}\rightleftharpoons 2N{{O}_{(g)}}\] is \[4\times {{10}^{-4}}\] at 200 K. In the presence of a catalyst, the equilibrium is attained 10 times faster. Therefore, the equilibrium constant in the presence of the catalyst at 200 K is:

    A) \[4\times {{10}^{-3}}\]

    B) \[4\times {{10}^{-4}}\]

    C) \[4\times {{10}^{-5}}\]

    D) none of these

    Correct Answer: C

    Solution :

    [b] Catalyst simply helps in attaining equilibrium earlier.
