Q. The most favourable condition for the manufacture of $NH_{3}$ is
A) high temperature and high pressure
B) low temperature and low pressure
C) high temperature and low pressure
D) low temperature and high pressure
Explanation
(d)
$N_{2}(g) + 3H_{2}(g) \rightleftharpoons 2NH_{3};\ \mathrm{\Delta}H = - 92.38\ kJ\ {mol}^{- 1}$
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.
