Question

For the reaction N2(g) + 3H2(g) 2NH3(g), what will happen if more ammonia gas is added?

Answer 1

If more ammonia is added... Equilibrium will shift to the left (reactant) according to LCP...

Answer is D

LCP, Le Chateliers Principle would do the opposite to what is to happen such as to re establish equilibrium. 

Answer 2

Answer:

The correct answer is option d.

Explanation:

$2N_2+3H_2\rightleftharpoons 2NH_3$

Any change in the equilibrium is studied on the basis of Le-Chatelier's principle.Whenever we increase the concentration of any species in an equilibrium ,there is a shift in an equilibrium in the direction where decrease in concentration is taking place.

So, when we add ammonia gas into the system , equilibrium will get shift in backward direction that is towards reactants.
