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

What happens to equilibrium when pressure is increased in a gaseous reaction?

Back

The equilibrium shifts towards the side with fewer moles of gas.

Front

What effect does adding a reactant have on the equilibrium position?

Back

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

Front

What happens to equilibrium when a product is added?

Back

Adding a product shifts the equilibrium to the left, favoring the formation of reactants.

Front

How does removing a reactant affect the equilibrium?

Back

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

Front

What is the effect of increasing temperature on an exothermic reaction?

Back

Increasing temperature shifts the equilibrium to the left, favoring the reactants.

Front

What is the effect of decreasing temperature on an exothermic reaction?

Back

Decreasing temperature shifts the equilibrium to the right, favoring the products.

Front

What happens to equilibrium when heat is removed from an exothermic reaction?

Back

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

Front

What is the effect of adding an inert gas to a reaction at equilibrium?

Back

Adding an inert gas at constant volume has no effect on the position of equilibrium.

Front

What is the role of catalysts in chemical reactions?

Back

Catalysts speed up the rate of reaction but do not affect the position of equilibrium.
