Question

Who coined the law of active mass?
A. Golberg and Waag
B. Lowry and Bronsted
C. Boyle and Arrhenius
D. Lewis and Sorensen

Answer 1

Law of mass action or law of active mass is going to explain the relationship between reactants and the rate of the chemical reaction. The concentration of the reactants is directly proportional to the rate of the chemical reaction.

Complete answer:
- In the question it is asked to find the scientist's name who coined the law of active mass.
- Generally there is a relationship between the concentration of the chemical reactants and the rate of the chemical reaction.
- The relationship is, the product of the concentration of the reactants is directly proportional to the rate of the chemical reaction and the relationship is mentioned as below with a proper chemical reaction.
- Consider a chemical reaction
$A+B\to Products$
- The law of active or mass action for the above mentioned chemical equation is as follows.
$r\alpha [A][B]$
Here r = rate of the chemical reaction
[A] = Concentration of the reactant A
[B] = Concentration of the reactant B
- Therefore the law of mass active is going to explain the rate of the chemical reaction with the help of the concentration of the chemical reactants. -
- The term law of active mass was coined by M. Guldberg and Peter Waage in the period of 1864-1879.

So, the correct option is A.

Note:
As the concentration of the reactants is going to increase the rate of the chemical also increases and the concentration of the reactants decreases then the rate of the chemical reaction is going to decrease. They are directly proportional to each other.
