03 Chemical equilibrium

  • A dynamic state reached in a reversible reaction when the rate of the forward reaction equals the rate of the backward reaction, and the concentrations of all reactants and products stay constant.
  • All substances remain in the reaction medium (no gas escapes, no precipitate forms).
  • The position of equilibrium does not change as long as the conditions (temperature, pressure, and so on) are unchanged.
  • Equal rates do not mean equal concentrations.
