Question

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

a.)There will be a shift toward the products.
b.)The value for Keq will change.
c.)There will not be a shift in equilibrium.
d.)There will be a shift toward the reactants.

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

The correct answer is option d.

Step-by-step 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.
