Law of Mass Action and Equilibrium Constant

Kc and Kp, relation between Kc and Kp

1. Law of Mass Action

  1. The Law of Mass Action states that the rate of a chemical reaction is directly proportional to the product of the concentrations of the reactants raised to their respective stoichiometric coefficients.
  2. For a reversible reaction: aA + bB ⇌ cC + dD, the equilibrium expression is:
