Equilibrium:The state of a chemical reaction where the rates of the forward and reverse reactions are equal, resulting in a constant composition of the reactants and products.
Reverse Reaction:The reaction that proceeds from the products back to the reactants, occurring simultaneously with the forward reaction in an equilibrium system.
Le Châtelier's Principle:The principle that states when a chemical system at equilibrium is subjected to a change in one of the conditions (concentration, temperature, or pressure), the system will shift to counteract the change and establish a new equilibrium.
