Le Châtelier’s Principle

Front

What is Le Châtelier’s Principle?

Back

Le Châtelier’s Principle states that if a dynamic equilibrium is disturbed by changing the conditions, the position of equilibrium shifts to counteract the change.

What happens to equilibrium when the volume of a container is increased?

Back

Increasing the volume of a container shifts the equilibrium towards the side with more moles of gas.

Front

What is the effect of adding a reactant to a system at equilibrium?

Back

Adding a reactant shifts the equilibrium towards the products.

Front

What is the effect of removing a product from a system at equilibrium?

Back

Removing a product shifts the equilibrium towards the products.

Front

How does temperature affect equilibrium in exothermic reactions?

Back

In exothermic reactions, increasing the temperature shifts the equilibrium towards the reactants.

Front

How does temperature affect equilibrium in endothermic reactions?

Back

In endothermic reactions, increasing the temperature shifts the equilibrium towards the products.

What happens when sodium ions (Na+) are added to a reaction at equilibrium?

Back

The addition of sodium ions can shift the equilibrium towards the reactants, depending on the specific reaction.

Front

What is the effect of pressure on equilibrium involving gases?

Back

Increasing pressure shifts the equilibrium towards the side with fewer moles of gas.

Front

What is a dynamic equilibrium?

Back

A dynamic equilibrium is a state in which the rate of the forward reaction equals the rate of the reverse reaction.

Front

What is the role of catalysts in chemical equilibrium?

Back

Catalysts speed up the rate of both the forward and reverse reactions but do not affect the position of equilibrium.
