For the reversible reaction (AIPMT 2014) N (g) 3H (g) 2NH (g) Heat The equilibrium shifts in forward direction
A.by increasing the concentration of
B.by decreasing the pressure.
C.by decreasing the concentration of
D.by increasing pressure and decreasing temperature.✓ Correct
Explanation
According to the Le-Chatelier’s principle, for an exothermic reaction, with the decrease in the temperature, the reaction is favoured in the forward reaction. And with the increase in pressure, the reaction is favoured in the direction where lesser number moles are present. Hence, the given reaction will shift in forward direction with decrease in temperature and increase in pressure.
