Problem

The concept of chemical equilibrium is very important.

Which one of the following statements is the most correct way to think about equilibrium?

(a) If a system is at equilibrium, nothing is happening.

(b) If a system is at equilibrium, the rate of the forward reaction is equal to the rate of the back reaction.

(c) If a system is at equilibrium, the product concentration is changing over time.
