A) \[\Delta H<\Delta E\]
B) \[\Delta H=\Delta E\]
C) \[\Delta H>\Delta E\]
D) none of these
Correct Answer: A
Solution :
\[\underset{1\,mol}{\mathop{{{N}_{2(g)}}}}\,+\underset{3\,mol}{\mathop{3{{H}_{2}}(g)}}\,-\underset{2\,mol}{\mathop{2N{{H}_{3(g)}}}}\,\] We know that \[\Delta H=\Delta E+P\Delta V=\Delta E+\Delta nRT\] Here, \[\Delta n=2-(1+3)=-2\] Therefore, \[\Delta H<\Delta E\]You need to login to perform this action.
