What happens to the equilibrium position if the concentration of a reactant is increased?

According to Le Chatelier’s principle, the equilibrium shifts in the direction that consumes the added reactant to re-establish equilibrium.

Why does a catalyst not affect the position of equilibrium?

A catalyst speeds up both the forward and reverse reactions equally, so it does not change the relative concentrations of reactants and products at equilibrium. It only helps the system reach equilibrium faster. Related Questions: Differentiate between reversible and irreversible reactions? State Le-Chatelier’s principle.

What is the significance of the equilibrium constant (Kc)?

The equilibrium constant (Kc) expresses the ratio of the concentrations of products to reactants at equilibrium. It indicates whether products or reactants are favored in the reaction.

State Le-Chatelier’s principle.

Le-Chatelier’s principle : If a system at equilibrium is subjected to a change in concentration, temperature, or pressure, the equilibrium will shift to counteract the imposed change and establish a new equilibrium, this phenomenon is known as Le-Chatelier’s principle.

Differentiate between reversible and irreversible reactions?

Reversible Reaction: A reaction that occurs in both forward and reverse directions (e.g., N₂ + 3H₂ ⇌ 2NH₃). Irreversible Reaction: A reaction that proceeds in one direction only (e.g., combustion of fuel). Related Questions: State Le-Chatelier’s principle.
