Q. In the following Haber synthesis of $NH_{3}$, the equilibrium constant for $NH_{3}$ formation, on increase in temperature, is
$N_{2}\left(g\right)+3H_{2}\left(g\right) {\rightleftharpoons} 2NH_{3} (g) +$ heat energy

UPSEEUPSEE 2011Equilibrium

Solution:

$N _{2}(g)+3 H _{2}(g) \rightleftharpoons 2 NH _{3}(g)+$ heat

energy. The given reaction is exothermic and equilibrium constant for an exothermic reaction decreases with rise in temperature.
