Chemical equilibrium refers to a dynamic state in a reversible reaction where the rates of the forward and reverse reactions are equal. This means that the concentration of reactants and products remains constant over time, even though the reactions are still occurring. At this point, the system has reached a balance, and while the individual molecules continue to react, their overall amounts do not change.

This concept is crucial in understanding reaction dynamics, as equilibrium does not imply that the concentrations of reactants and products are equal, only that their rates of formation are balanced. Thus, the system can involve different amounts of reactants and products, but as long as their rates of conversion are equal, equilibrium is achieved.

The misconception that all reactants are converted to products does not hold true for equilibrium; instead, some reactants and products coexist. Similarly, the idea that equilibrium requires all substances to be gaseous is incorrect, as equilibrium can occur in any state of matter (solids, liquids, gases). Lastly, equilibrium is a stable state rather than a temporary one, as it represents a sustained condition in the reaction process.
