# A student says: 'Once a reversible reaction reaches equilibrium, the reaction has stopped.' Explain why the student is wrong.

> AQA GCSE Chemistry (8462) — 4.6.2 Reversible reactions and dynamic equilibrium · Explain · 4 marks

## Mark scheme (4 marks)

1. At equilibrium, the forward reaction is still occurring / has not stopped
2. At equilibrium, the reverse reaction is also still occurring / has not stopped
3. The forward and reverse reactions occur at exactly the same rate
4. So the concentrations / amounts of reactants and products remain constant
