Question

Law of Mass action was given by?

• A. Avogadro
• B. Michelles-Menten
• C. Guldberg-Waage
• D. None of these

Answer 1

Answer: (C)

Guldberg-Waage

Option C is the correct answer.

Law of mass action was given by Guldberg and Waage in the 1860s.

It states that the rate of a chemical reaction is directly proportional to the concentration of the reactants with their powers raised to their stoichiometric coefficient in the reaction.

For the reaction :

$3A$$+$$2B$$=$$2C$$+$$3D$

Thus the law of mass action can be written as :

$Rate$$=$$k$$[A{]}^3$$[B{]}^2$
