According to the 'law of mass action', the rate of reaction is directly proportional to the__________________?
Correct answer: D. Molar concentration of the reactants
- A. Equilibrium constant
- B. Volume of the reaction vessel
- C. Nature of the reactants
- D. Molar concentration of the reactants
Explanation
The law of mass action relates reaction rate to the active masses, commonly represented by the molar concentrations, of the reacting species. The concentrations are raised to powers determined by the reaction kinetics or, for an elementary reaction, its stoichiometry.
