  • Chemical Equilibrium
    A dynamic state where the rates of forward and reverse reactions are equal, causing concentrations of reactants and products to remain constant.
  • Equilibrium Constant
    A value calculated from the ratio of product to reactant concentrations, each raised to their coefficients, indicating reaction favorability.
  • Forward Rate
    The speed at which reactants are converted into products, initially high but decreases as reactants are consumed.
  • Reverse Rate
    The speed at which products revert to reactants, starting at zero and increasing as product concentration builds.
  • Rate Constant
    A proportionality factor unique to each reaction direction, relating reaction rate to reactant or product concentrations.
  • Equilibrium Expression
    A mathematical formula showing the ratio of product to reactant concentrations, each raised to their respective coefficients.
  • Reactant Concentration
    The amount of starting substances present in a reaction mixture, typically decreasing as the reaction proceeds.
  • Product Concentration
    The amount of substances formed from reactants, increasing until equilibrium is reached.
  • Directionality
    The tendency of a reaction to favor either products or reactants, determined by the magnitude of the equilibrium constant.
  • Plateau
    A point on a concentration versus time graph where reactant and product amounts stabilize, indicating equilibrium.
  • Ideal Equilibrium
    A scenario where the equilibrium constant equals one, meaning neither products nor reactants are favored.
  • Equilibrium State
    A condition where the system's macroscopic properties remain unchanged due to equal forward and reverse reaction rates.
  • Magnitude of K
    A measure indicating whether products or reactants are favored at equilibrium, based on whether the value is greater or less than one.
  • Equilibrium Concentration
    The specific amounts of reactants and products present when the reaction has reached equilibrium.
