At chemical equilibrium, forward and reverse processes continue but their rates are equal, so macroscopic composition no longer changes with time. Equilibrium is dynamic, not a frozen reaction.
That single idea prevents one of the most common misunderstandings in chemistry.

Choose a concrete case linked to Chemical equilibrium. Write down the known information, what you are trying to find, and the units. Then state the rule, model or trend you will use. If a calculation is involved, keep the units visible at every line; if it is conceptual, state what changes and what remains fixed.
A strong answer contains four things: the starting situation, the variable that changes, the direction or numerical result, and one check. The check can be a unit, an order of magnitude, a limiting case or a comparison with a familiar example.
