Equilibrium Constant (Keq): The ratio of product concentrations to reactant concentrations at equilibrium, with each concentration raised to a power equal to the number of moles in the balanced chemical equation.
Le Chatelier’s Principle: A principle stating that if a system at equilibrium experiences a change in concentration, temperature, volume, or partial pressure, then the equilibrium shifts to counteract the imposed change.
Reaction Quotient (Q): A measure comparing the current state ratios of products and reactants with respect to their stoichiometric coefficients.
