A) high temperature and high pressure
B) low temperature and low pressure
C) high temperature-and low pressure
D) low temperature and high pressure
Correct Answer: D
Solution :
Key Idea: Use Le-Chatelier principle \[{{N}_{2}}(g)+3{{H}_{2}}(g)2N{{H}_{3}}\] \[\Delta H=-92.38\,kJ\,\,mo{{l}^{-1}}\] In forward reaction, the volume decreases and it is exothermic reaction. According to Le-Chatelier principle, such reactions are favoured at low temperature and high pressure.
