Reversible Reactions and Equilibrium — Quiz

Question 10 • Chemistry

Which statement correctly describes a reaction in dynamic equilibrium?

Answer
A
At dynamic equilibrium, the reactions continue and the amounts of reactants and products are changing.
B
At dynamic equilibrium, the reactions continue but the amounts of reactants and products do not change.
C
At dynamic equilibrium, the reactions stop and the amounts of reactants and products do not change.
D
At dynamic equilibrium, the reactions stop but the amounts of reactants and products are changing.

Explanation

At dynamic equilibrium, the forward and reverse reactions continue at equal rates. Because they balance each other, the amounts of reactants and products stay constant over time, though they are not necessarily equal. Therefore, the correct statement is that reactions continue but the amounts do not change.
