Question

Which of the following happens when a reaction reaches dynamic equilibrium in a closed system? aThe concentrations of the reactants and products increase. bThe concentrations of the reactants and products decrease. cThe rate of the forward reaction equals the rate of the reverse reaction. dThe rate of the forward reaction is slower than the rate of the reverse reaction.

Answer 1

Step-by-step explanation:

A dynamic equilibrium is a chemical equilibrium between a forward reaction and a reverse reaction where the rate of the reactions are equal.

At this point, the ratio between reactants and products remains unchanged over time.

At dynamic equilibrium: r1 (forward rate) = r2 (reverse rate)

Answer: c The rate of the forward reaction equals the rate of the reverse reaction.
