Question

Consider the following reaction at equilibrium. What will happen if FeS2 is added to the reaction? 4FeS2(s) + 11O2(g) ⇌ 2Fe2O3(s) + 8SO2(g) Consider the following reaction at equilibrium. What will happen if is added to the reaction? 4(s) + 11(g) 2(s) + 8(g) The equilibrium constant will increase. The reaction will shift in the direction of the reactants. The reaction will shift in the direction of the products. No change in the position of the equilibrium is observed. The equilibrium constant will decrease.

Answer 1

If FeS₂ is added in the given reaction, then the reaction will shift in the direction of the products.

What is equilibrium law?

Equilibrium law state that if any external condition or material is added to any reaction if that reaction is present in the equilibrium, then the net reaction will move on that side which decreases the effect of the external thing.

In the given reaction 4FeS₂(s) + 11O₂(g) ⇄ 2Fe₂O₃(s) + 8SO₂(g), if we add FeS₂ at the equilibrium state then reaction will goes in forward direction for the formation of product to rectify the excess amount of FeS₂ in the reaction.

Hence, option (3) is correct i.e. it moves in the direction of products.
