It is experimentally found that catalyst is used to:
Correct answer: A. Lower the activation energy
- A. Lower the activation energy
- B. Increase the activation energy
- C. Lower the pH
- D. Decrease
Explanation
A positive catalyst increases rate of reaction, decreases activation energy, decreases equilibrium time and changes mechanism 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.
