    On increasing the pressure, the gas phase reaction proceed forward to re-establish equilibrium, as predicted by applying the Le-Chatelier's principle. Consider the reaction. \[{{N}_{2}}(g)+3{{H}_{2}}(g)2N{{H}_{3}}(g)\] Which of the following is correct, if the total pressure at which the equilibrium is established, is increased without changing the temperature?

    A) K will remain same

    B) K will decrease

    C) K will increase

    D) K will increase initially and decrease when pressure is very high

    Correct Answer: A

    Solution :

    [a] Justification: According to Le-Chatelier's principle, at constant temperature, the equilibrium composition will change but K will remain same.
