Question

The law of mass action states that, at a given temperature, the rate of a chemical reaction is directly proportional to the product of the molar concentrations of the reactants with their powers raised to their stoichiometric coefficient. The molar concentration of the reactant is also known as the:

• A. active mass
• B. total mass
• C. molecular mass
• D. none of these

Answer 1

Answer: (A)

active mass

The mass of electron is one which is active in the reaction.
so, 17 is called active mass (option A).
