Which is not true about rate of reaction?
Correct answer: A. It is independent of concentration of reactants.
- A. It is independent of concentration of reactants.
- B. It depends upon the temperature.
- C. It does not depend upon the order of reaction.
- D. All of the above options are correct.
Explanation
Option a) "It is independent of the concentration of reactants" is not true about the rate of reaction. The rate of a chemical reaction is typically dependent on the concentration of reactants. In fact, one of the fundamental principles of chemical kinetics is the relationship between the rate of reaction and the concentrations of reactants, often expressed in the form of rate laws.

About Rate of Reaction
Reaction rate measures the change in concentration of a reactant or product per unit time. Questions connect rate with concentration, temperature, pressure, surface area, catalysts and nature of reactants, and may involve rate laws, reaction order, activation energy and collision theory. Rate describes speed, whereas equilibrium describes the final balance of opposing reactions.
