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.

What happens to equilibrium when heat is added to an exothermic reaction?

Back

The equilibrium shifts left, towards the reactants.

Front

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

Back

The equilibrium shifts right, towards the products.

Front

What effect does adding a reactant have on equilibrium?

Back

Adding a reactant shifts the equilibrium to the right, towards the products.

Front

What effect does adding a product have on equilibrium?

Back

Adding a product shifts the equilibrium to the left, towards the reactants.

Front

What happens to equilibrium when a reactant is removed?

Back

Removing a reactant shifts the equilibrium to the left, towards the reactants.

Front

What happens to equilibrium when a product is removed?

Back

Removing a product shifts the equilibrium to the right, towards the products.

Front

How does pressure affect equilibrium in gaseous reactions?

Back

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

Front

What is the effect of temperature on equilibrium in an endothermic reaction?

Back

Increasing temperature shifts the equilibrium to the right, towards the products.
