Le Chatlier'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.

What happens to the equilibrium when products are added?

Back

The reaction will shift toward the reactants.

Front

What happens to the equilibrium when reactants are added?

Back

The reaction will shift toward the products.

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

Back

The equilibrium will shift toward the left, favoring the formation of reactants.

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

Back

The equilibrium will shift toward the right, favoring the formation of products.

Front

What happens to the equilibrium when the volume of the container is decreased?

Back

The equilibrium will shift toward the side with fewer moles of gas.

Front

What happens to the equilibrium when the temperature is increased in an exothermic reaction?

Back

The equilibrium will shift to the left, favoring the reactants.

Front

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

Back

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

Front

What is the effect of increasing pressure on a system at equilibrium?

Back

The equilibrium will shift toward the side with fewer moles of gas.
