____________ accounts for the equilibrium constant associated with any chemical reaction?
Show answer Hide answer
Answer: B. Law of mass action
Explanation
The law of mass action states that a chemical reaction rate is proportional to reactant concentrations. Applying this fundamental principle to reversible reactions yields the mathematical equilibrium constant expression. Therefore, the law of mass action directly accounts for the equilibrium constant of any reaction. Formulated by Guldberg and Waage, the law relates concentrations of products and reactants at equilibrium. The equilibrium constant is temperature-dependent and remains constant for a specific reaction. This law is a cornerstone of chemical thermodynamics and reaction kinetics studies.
Chemical engineers use equilibrium constants to maximize product yields in industrial synthesis reactors. Understanding chemical equilibrium helps pharmaceutical scientists optimize drug formulation reactions. Students learn the law of mass action in chemistry to predict the direction of reversible reactions. Henry law describes the dissolution of gases in liquids relative to their partial pressures. Hess law relates enthalpy changes of reactions regardless of the pathway taken. The option stating none of these is incorrect because the law of mass action is correct.
