    In Haber process 30 L of dihydrogen and 30 L  of dinitrogen were taken for reaction which yielded only 50% of the expected product. What will be the composition of gaseous mixture under the aforesaid condition in the end?       [AIPMT 2003]

    A) 20 L ammonia, 10 L nitrogen, 30 L hydrogen

    B)       20 L ammonia, 25 L nitrogen, 15 L hydrogen

    C)       20 L ammonia, 20 L nitrogen, 20 L hydrogen

    D)       10 L ammonia, 25 L nitrogen, 15 L hydrogen

    Correct Answer: D

    Solution :

               
    \[\begin{matrix}    {{N}_{2}} & + & 3{{H}_{2}} & \xrightarrow{{}} & 2N{{H}_{3}}  \\    \text{or}\,\,\text{1}\,\text{mole} & {} & 3\,\text{mole} & {} & 2\,\text{mole}  \\    \text{or}\,\,_{2}^{1}\,\text{mole} & {} & _{2}^{3}\,\text{mole} & {} & 1\,\text{mole}  \\ \end{matrix}\]
    Composition of gaseous mixture under the aforesaid condition in the end
    \[{{H}_{2}}=30-15=15\,L\]
    \[{{N}_{2}}=30-5=25\,L\]
    \[N{{H}_{3}}=10\,L\]
