Le Chatelier Quick Check

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 the equilibrium position when temperature is increased in an exothermic reaction?

Back

The equilibrium position shifts to the left, favoring the reactants.

Front

What happens to the equilibrium position when water is added to a reaction involving aqueous solutions?

Back

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

Front

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

Back

Increasing the volume shifts the equilibrium position towards the side with more moles of gas.

Front

What are the factors that affect the position of equilibrium?

Back

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

Front

What is the effect of adding a reactant to a system at equilibrium?

Back

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

Front

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

Back

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

Front

What is the effect of increasing pressure on a gaseous equilibrium?

Back

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

Front

What is the role of temperature in an endothermic reaction at equilibrium?

Back

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

Front

What does it mean when a reaction is at equilibrium?

Back

At equilibrium, the rates of the forward and reverse reactions are equal, and the concentrations of reactants and products remain constant.
