Le Chatelier's Principle

Front

What is Le Chatelier's Principle?

Back

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

Front

How does adding a reactant affect equilibrium?

Back

Adding a reactant shifts the equilibrium to the right, favoring the formation of products.

Front

What happens to equilibrium when a product is removed?

Back

Removing a product shifts the equilibrium to the right, favoring the formation of more products.

Front

What effect does increasing pressure have on gaseous equilibria?

Back

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

Front

How does temperature affect exothermic reactions at equilibrium?

Back

Increasing temperature shifts the equilibrium to the left, favoring the reactants in exothermic reactions.

Front

What is the effect of a catalyst on equilibrium?

Back

A catalyst speeds up the rate of reaching equilibrium but does not affect the position of equilibrium.

Front

What is the relationship between concentration and equilibrium?

Back

Changing the concentration of reactants or products will shift the equilibrium position to restore balance.

Front

What occurs when heat is added to an endothermic reaction at equilibrium?

Back

Adding heat shifts the equilibrium to the right, favoring the formation of products.

Front

What is the effect of decreasing the concentration of a reactant?

Back

Decreasing the concentration of a reactant shifts the equilibrium to the left, favoring the formation of reactants.

Front

How does the addition of an inert gas affect equilibrium?

Back

Adding an inert gas at constant volume does not affect the equilibrium position.
