Chemical equilibrium is the state where chemical reactions are in balance and no longer occurring.

Question

BlackTom AI · Accepted Answer

The statement describes chemical equilibrium as a state where reactions are in balance and no longer occurring, which is not accurate.
Option 1 (True): This would imply that reactions stop completely at equilibrium. In reality, at equilibrium, the forward and reverse reaction rates are equal, but both reactions continue to occur at the same rate. So the statement is incorrect.
Option 2 (False): This correctly captures the idea that although there is a balance of rates, the chemical processes themselves are still taking place. Substances may be interconverting, and the system maintains constant concentrations because the opposing processes balance each other. Therefore, the statement is false.
