    For \[{{N}_{2(g)}}+3{{H}_{2(g)}}2N{{H}_{3}}(g),\,\Delta H\] is equal to

    A)  \[\Delta E+2RT\]       

    B)  \[\Delta E-2RT\]

    C)  \[\Delta E+RT\]         

    D)  \[\Delta E-RT\]

    Correct Answer: B

    Solution :

    \[\Delta H=\Delta E+\Delta ngRT\] For the reaction, \[{{N}_{2(g)}}+3{{H}_{2(g)}}2N{{H}_{3(g)}}\] \[\Delta {{n}_{g}}=2-4=-2\] \[\Delta H=\Delta E+(-2)RT\] \[\Delta H=\Delta E-2RT\]
