Chemical Equilibrium Concepts

Front

What is Chemical Equilibrium?

Back

A state in a chemical reaction where the rates of the forward and reverse reactions are equal, resulting in constant concentrations of reactants and products.

Front

What are the two key factors to determine if a reaction is at equilibrium?

Back

The forward and reverse reaction rates are equal, and the amounts of reactants and products remain constant.

Front

At what point is equilibrium established in a reaction?

Back

Equilibrium is established when the rates of the forward and reverse reactions become equal.

Front

What does it mean when the forward reaction rate is equal to the reverse reaction rate?

Back

It indicates that the system is in Chemical Equilibrium.

Front

Which statement is NOT true at equilibrium?

Back

The amount (concentration) of the reactants is equal to the concentration of the products.

Front

What happens to the concentrations of reactants and products at equilibrium?

Back

The concentrations remain constant over time.

Front

Can reactions continue to occur at equilibrium?

Back

Yes, both forward and reverse reactions continue to occur at equilibrium.

Front

What is the significance of the equilibrium constant (K)?

Back

It quantifies the ratio of concentrations of products to reactants at equilibrium.

Front

How does temperature affect chemical equilibrium?

Back

Changes in temperature can shift the position of equilibrium, favoring either the forward or reverse reaction.

Front

What is Le Chatelier's Principle?

Back

If a system at equilibrium is subjected to a change in concentration, temperature, or pressure, the system will adjust to counteract that change.
