    In the synthesis of ammonia \[{{N}_{2}}(g)+3{{H}_{2}}\rightleftharpoons 2N{{H}_{3}}(g)\] When 100 ml. of \[{{\text{N}}_{\text{2}}}\] has reacted, the volume of \[{{H}_{2}}\] which has also reacted and ammonia produced are:

    A) \[\text{300 ml}\text{. }{{\text{H}}_{\text{2 }}}\]and \[\text{200 ml}\text{. N}{{\text{H}}_{\text{3}}}\]

    B) \[\text{ }\!\!~\!\!\text{ 300 ml}\text{. }{{\text{H}}_{\text{2}}}\] and \[\text{300 ml}\text{. N}{{\text{H}}_{\text{3}}}\]

    C) \[\text{100 ml}\text{. }{{\text{H}}_{\text{2}}}\]and \[\text{100 ml}\text{. N}{{\text{H}}_{\text{3}}}\]

    D) \[\text{100 ml}\text{. }{{\text{H}}_{\text{2}}}\]and \[\text{200 ml}\text{. N}{{\text{H}}_{\text{3}}}\]

    Correct Answer: A

    Solution :

    \[{{N}_{2}}(g)+3{{H}_{2}}(g)=2N{{H}_{3}}(g)\] The quantity of\[{{N}_{2}}(g)\]reacted =100 ml \[\therefore \]The quantity of \[{{H}_{2}}(g)\]is three times =300 ml and NHs produced \[=200\text{ }ml\]
