    \[{{N}_{2}}+3{{H}_{2}}2N{{H}_{3}}+22.4\,k\,cal\] What are the favourable condition for the formation of ammonia in the above reaction?

    A)  High temperature and low pressure

    B)  Low temperature and high pressure

    C)  High temperature and high pressure

    D)  Low temperature and low pressure

    Correct Answer: B

    Solution :

     \[{{N}_{2}}+3{{H}_{2}}2N{{H}_{3}}+22.4\,kcal\] This is exothermic reaction and number of moles are decreasing during the formation of product from reactant. \[\left( n\propto \frac{1}{p} \right).\] Hence, low temperature and high pressure are favourable condition for the formation of ammonia.
