Equilibrium Flashcards

All 5 cards in this deck

When is a reversible reaction at equilibrium?

When the forward and reverse reactions occur at exactly the same rate.

What is a closed system in the context of equilibrium?

Apparatus that prevents reactants and products escaping (or entering).

True or false? At equilibrium both reactions have stopped.

False. Both reactions carry on, but at exactly the same rate, so the amounts do not change.

True or false? At equilibrium the amounts of reactants and products are always equal.

False. Their concentrations stay constant, but they are usually not equal to each other.

What happens to the concentrations of the substances once equilibrium is reached?

They stay constant, because the forward and reverse reactions occur at the same rate.
