Equilibrium Ques 19
19. For the reversible reaction,
$N_2(g)+3 H_2(g) \rightleftharpoons 2 NH_3(g)+$ heat
[2014]
The equilibrium shifts in forward direction
(a) By increasing the concentration of $NH_3(g)$
(b) By decreasing the pressure
(c) By decreasing concentration of $N_2(g)$ and $H_2(g)$
(d) By increasing pressure and decreasing temperature.

Answer:
Correct Answer: 19.(d)
Solution:
- (d) Given reaction is exothermic reaction. Hence according to Le-Chatelier’s principle low temperature favours the forward reaction and on increasing pressure equilibrium will shift, towards lesser number of moles i.e. forward direction.
