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. It is fundamental in understanding how reactions proceed and reach equilibrium.
5 Must Know Facts For Your Next Test
1. The law of mass action helps predict how changes in concentration affect reaction rates.
2. It is crucial for understanding dynamic equilibrium in reversible reactions.
3. The law can be expressed with the equilibrium constant (K_eq), which relates the concentrations of products and reactants at equilibrium.
4. The principle assumes ideal behavior, where interactions between molecules are negligible.
5. It forms the basis for deriving rate laws used in chemical kinetics.
