Question

which statement correctly describes a reaction in dynamic equilibrium?
at dynamic equilibrium, the reactions stop and the amounts of reactants and products do not change.
at dynamic equilibrium, the reactions stop but the amounts of reactants and products are changing.
at dynamic equilibrium, the reactions continue but the amounts of reactants and products do not change.
at dynamic equilibrium, the reactions continue and the amounts of reactants and products are changing.

Explanation:

En un equilibrio dinámico, las reacciones directa e inversa continúan ocurriendo, pero la tasa de la reacción directa es igual a la tasa de la reacción inversa. Esto significa que aunque las reacciones no se detienen, las cantidades de reactivos y productos permanecen constantes (no cambian) porque lo que se forma en la reacción directa se consume en la reacción inversa y viceversa.

Answer:

At dynamic equilibrium, the reactions continue but the amounts of reactants and products do not change.
