Le Chatelier's Principle: A principle stating that if a change in conditions is imposed on a system at equilibrium, the system will adjust itself to partially counteract the change.
Reaction Quotient (Q):A measure similar to Keq but for non-equilibrium conditions. It helps predict which direction a reaction will proceed to reach equilibrium.
Chemical Equilibrium:The state where concentrations of reactants and products remain constant over time because their rates of reaction are equal.
