Equilibrium Review

Front

What happens to the rates of the forward and reverse reactions at equilibrium?

Back

They are the same.

Front

Define chemical equilibrium.

Back

Chemical equilibrium is the state in which the rate of the forward reaction is equal to the rate of the reverse reaction.

Front

How does a catalyst affect a chemical reaction?

Back

A catalyst remains unchanged during the reaction.

Front

What is NOT true at equilibrium?

Back

The concentration of the reactants is equal to the concentration of the products.

Front

How long does it take to establish equilibrium in a reaction?

Back

It can vary, but in this context, it is stated as 5 seconds.

Front

What is the significance of equilibrium in a chemical reaction?

Back

Equilibrium indicates that the reaction has reached a state where the concentrations of reactants and products remain constant over time.

Front

What factors can affect the position of equilibrium?

Back

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

Front

What is Le Chatelier's Principle?

Back

Le Chatelier's Principle states that if a system at equilibrium is subjected to a change in concentration, temperature, or pressure, the system will adjust to counteract that change.

Front

What is the difference between dynamic and static equilibrium?

Back

Dynamic equilibrium involves ongoing processes with no net change, while static equilibrium involves no movement or change.

Front

How can you shift the equilibrium position to favor products?

Back

By increasing the concentration of reactants, decreasing the concentration of products, or changing temperature and pressure appropriately.
