Equilibrium: A state in a reversible chemical reaction where the concentrations of reactants and products remain constant over time because the forward and reverse reactions occur at equal rates.
Dynamic Equilibrium: The condition where, despite constant reactions occurring in both directions, the overall concentrations of reactants and products do not change, indicating a continuous but balanced process.
Equilibrium Constant (K): A numerical value that expresses the ratio of concentrations of products to reactants at equilibrium, each raised to the power of their stoichiometric coefficients; it indicates the position of equilibrium at a specific temperature.
Le Chatelier's Principle: A principle stating that if a system at equilibrium experiences a change in concentration, temperature, or pressure, the system will adjust to partially counteract that change and establish a new equilibrium.
