Question: Which of the following statements about dynamic equilibrium is true?

Options:

1. The concentrations of reactants and products are equal
2. The rate of the forward reaction equals the rate of the reverse reaction
3. The reaction has stopped
4. The system is at rest

Correct Answer: The rate of the forward reaction equals the rate of the reverse reaction

Solution:

In dynamic equilibrium, the rates of the forward and reverse reactions are equal, but the concentrations of reactants and products may not be equal.
