The addition of catalyst to a reaction can.
Correct answer: D. Change the activation energy
- A. Change the enthalpy
- B. Change the entropy
- C. Change the nature of products
- D. Change the activation energy
Explanation
Option D is the most accurate statement. A catalyst provides an alternative reaction pathway with a lower activation energy. By lowering the activation energy, a catalyst speeds up the rate of the reaction without itself being consumed. This allows the reaction to occur more readily under milder conditions.

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.
