Le Chatelier's Principle and Equilibrium

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 the concentration of a reactant is increased?

Back

The position of equilibrium shifts to the right, favoring the formation of products.

Front

What happens to equilibrium when the concentration of a product is decreased?

Back

The position of equilibrium shifts to the right, favoring the formation of more products.

Front

How does increasing the temperature affect an exothermic reaction at equilibrium?

Back

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

Front

How does decreasing the volume of a gas reaction at equilibrium affect the position of equilibrium?

Back

Decreasing the volume shifts the equilibrium towards the side with fewer moles of gas.

Front

What effect does adding an inert gas at constant volume have on equilibrium?

Back

Adding an inert gas does not affect the position of equilibrium.

Front

What is the effect of pressure on equilibrium when there are equal moles of gas on both sides?

Back

Changing the pressure has no effect on the position of equilibrium.

Front

What is the effect of removing a reactant on the position of equilibrium?

Back

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

Front

What is the effect of adding a catalyst on equilibrium?

Back

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

Front

What are the factors that affect the position of equilibrium?

Back

Concentration, pressure, and temperature affect the position of equilibrium.
