  • Equilibrium Constant
    A numerical value expressing the ratio of product to reactant concentrations at a specific temperature for a chemical reaction.
  • K
    A symbol representing the equilibrium constant, indicating the extent to which a reaction favors products or reactants.
  • Ratio
    A comparison of the concentrations of products to reactants, used to determine the value of the equilibrium constant.
  • Temperature
    A factor that directly influences the magnitude of the equilibrium constant, with increases raising and decreases lowering its value.
  • Products
    Substances formed as a result of a chemical reaction, whose concentration is used in the numerator when calculating the equilibrium constant.
  • Reactants
    Starting substances in a chemical reaction, whose concentration is used in the denominator when calculating the equilibrium constant.
  • Forward Direction
    The progression of a reaction toward forming more products, favored when the equilibrium constant is greater than one.
  • Reverse Direction
    The progression of a reaction toward forming more reactants, favored when the equilibrium constant is less than one.
  • Magnitude
    The size or value of the equilibrium constant, indicating whether products or reactants are favored at equilibrium.
  • State of Matter
    A physical form—solid, liquid, or gas—of substances, with only gases and aqueous species considered in equilibrium constant calculations.
  • Solids
    A state of matter excluded from equilibrium constant calculations due to unchanging concentration during reactions.
  • Liquids
    A state of matter not included in equilibrium constant calculations, as their concentration remains constant in reactions.
  • Balanced State
    A condition where the amounts of products and reactants are equal, corresponding to an equilibrium constant value of one.
