The experimental relationship between rate of reaction and concentration of reactant is called:
Correct answer: A. Rate Law
- A. Rate Law
- B. Hess's Law
- C. Law of mass action
- D. Le-Chateliar's principle
Explanation
The rate law describes the relationship between the rate of a chemical reaction and the concentrations of its reactants. It is determined experimentally and helps to understand how changes in reactant concentrations influence the rate of the reaction. The rate law is expressed in terms of rate constants and the concentrations of reactants raised to certain powers (exponents).

About Reaction Kinetics
Reaction kinetics relates reaction rate to concentration, temperature, surface area and catalysts. Questions cover rate laws, reaction order, rate constants, activation energy and the activated complex, including how a catalyst lowers the activation energy without changing the overall energy change or equilibrium position.
