    What happens to the yield on application of high pressure in the Haber's synthesis of ammonia?

    A)  Increases       

    B)  Decreases

    C)  Unaffected      

    D)  Reaction stops

    Correct Answer: A

    Solution :

    Haber's process of synthesis of ammonia \[{{N}_{2}}+3{{H}_{2}}2N{{H}_{3}}\] Since, the number of molecules of gaseous products are less than the number of molecules of gaseous reactants,  thus according to Le-Chatelier's principle, high pressure favours the forward reaction i.e., more ammonia will be obtained.
