What is another word for mass-action principle?
Pronunciation: [mˈasˈakʃən pɹˈɪnsɪpə͡l] (IPA) 
The mass-action principle refers to the idea that the rate of a chemical reaction can be determined by the concentration of its reactants. It is also commonly known as the law of mass action. However, there are several other related terms and synonyms that are often used in chemistry. These include the law of chemical equilibrium, the principle of chemical equilibrium, the principle of chemical kinetics, and the principle of microchemical reactions. Essentially, all of these terms are describing the same fundamental concept in chemistry, which is the relationship between the concentration of reactants and the rate of a reaction. Whether you refer to it as the mass-action principle or any of its synonyms, the importance of this principle cannot be understated in the study of chemical reactions.
