"The rate at which a substance reacts is proportional to its active mass and the rate of a chemical reaction is proportional to the product of active masses of the reacting substances". This is the_________________?
Correct answer: B. None of these
- A. Lewis-Randall rule
- B. None of these
- C. Le-Chatelier's principle
- D. Statement of Van't Hoff Equation
Explanation
The statement describes the law of mass action, which says that reaction rate depends on the product of the reactants' active masses. Since the law of mass action is not listed, none of the options is the named principle.
