Question

The equation shows the formation of ammonia from nitrogen and hydrogen. How will increasing the temperature affect the equilibrium? A. more energy is released B. more ammonia forms C. the system is unaffected by the change D. more hydrogen and nitrogen form

Answer 1

Your answer is D.

Hope this helps:)

Answer 2

Answer: D. more hydrogen and nitrogen form

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:

$2N_2(g)+3H_2(g)\leftrightharpoons 2NH_3+energy$

This is a type of exothermic reaction because heat is released in the reaction.

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 forward reaction is exothermic reaction, it will increase the temperature and backward reaction being endothermic will decrease the temperature. Hence, the equilibrium will shift in the left or backward direction.

Thus more hydrogen and nitrogen will be formed.
