Which law states that the rate of a chemical reaction is proportional to the product of the active masses of the reacting substances, raised to the power, equal to the respective number of their molecules taking part in a reaction by the balanced chemical equation?
Answer & explanation
Correct answer: option 4
Law of mass action states that the rate of a chemical reaction is proportional to the product of the active masses of the reacting substances, raised to the power, equal to the respective number of their molecules taking part in a reaction by the balanced chemical equation.
Active mass = molar concentration of substance
= \(\frac{\text{no of gram-moles of substance}}{\text{volume in litres}}\)
