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 Chatelier's Principle
Explanation
The Rate Law is the correct choice because it defines the mathematical relationship between the concentration of reactants and the rate of a reaction, determined through experiments. This distinguishes it from Hess's Law, which deals with enthalpy changes; the Law of Mass Action, which is more about equilibrium concentrations; and Le Chatelier's Principle, which pertains to changes in equilibrium conditions, none of which describe the experimental relationship between reaction rate and concentration.

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.
