If a reaction rate does not change with concentration, then it is
Correct answer: D. Zero order
- A. 3rd order
- B. 2nd order
- C. Ist order
- D. Zero order
Explanation
The rate of a zero-order reaction is constant and does not depend on the concentration of the reactants. Thus, changing the concentration will not affect the rate of reaction.

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.
