Rate of reaction increases by the addition of catalyst:
Correct answer: C. Energy of activation decreases
- A. Catalyst reacts with reactant
- B. Catalysts reacts with product
- C. Energy of activation decreases
- D. Energy of activation increases
- E. Energy of activation
Explanation
Reaction rate increases by adding catalyst because it decreases activation energy, so Option C is the correct answer.

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.
