What happens to the rate of a reaction at equilibrium?

A. It increases indefinitely
B. It decreases to zero
C. It remains constant
D. It fluctuates

Answer: It remains constant

Additional Information: At equilibrium, the rate of the forward reaction equals the rate of the reverse reaction, resulting in a constant rate.
