  • question_answer
    Equilibrium constant \[{{K}_{c}}\] for the reaction \[2N{{H}_{3}}{{N}_{2}}+3{{H}_{2}}\]is given by the following:

    A)  \[\frac{{{[N{{H}_{3}}]}^{2}}}{[{{N}_{2}}]{{[{{H}_{2}}]}^{3}}}\]   

    B)  \[\frac{[{{N}_{2}}]{{[{{H}_{2}}]}^{3}}}{{{[N{{H}_{3}}]}^{2}}}\]

    C)  \[\frac{3{{[H]}_{2}}[{{N}_{2}}]}{2[N{{H}_{3}}]}\]

    D)  \[\frac{2[N{{H}_{3}}]}{{{[H]}_{2}}[{{N}_{2}}]}\]

    Correct Answer: B

    Solution :

    \[{{K}_{c}}=\frac{active\text{ }mass\text{ }of\text{ }product}{active\text{ }mass\text{ }of\text{ }reactant}\] \[{{K}_{c}}=\frac{[{{N}_{2}}]{{[{{H}_{2}}]}^{3}}}{{{[N{{H}_{3}}]}^{3}}}\]
