According to the law of mass action, the rate of an elementary reaction is directly proportional to the________of the reactants.

A

mole fractions

B

molalities

C

normalities

D

molarities

Text Solution

Verified by Experts

The correct Answer is:
D
According to law of mass action, the rate of an elementary reaction is directly proportional to the active mass of the reactants. For components of ideal solutions, the activity of each component is taken to be the ratio of its molar concentration to a standard concentration of `1M`.
