Answer:
The correct statements are (II) and (III).
Explanation:
Any change in the equilibrium is studied on the basis of Le-Chatelier's principle.
This principle states that if there is any change in the variables of the reaction, the equilibrium will shift in the direction to minimize the effect.
For the given equation:
This is a type of exothermic reaction because heat is released in the reaction.
On increasing the temperature
If the temperature is increased, so according to the Le-Chatlier's principle , the equilibrium will shift in the direction where decrease in temperature occurs. As, this is an exothermic reaction, forward reaction will increase the temperature. Hence, the equilibrium will shift in the left direction.
And by moving to left side amount of ammonia will decrease accompanied by the change in the value of an equilibrium constant.
