The rate of chemical reactions at constant temperature is directly proportional to the active concentration of the reaction this is according to:
a) Le-Chatliers principle
b) The distribution law
c) Law of constant proportions
d) Law of Mass Action
Explanation: The Law of Mass Action states that the rate of a chemical reaction at a constant temperature is directly proportional to the active concentration (molar concentration) of the reactants. This principle describes the relationship between the concentration of reactants and the rate at which a chemical reaction proceeds.
