Which type of energy does heat provide to activate a chemical reaction?
Correct answer: D. Kinetic energy
- A. Potential energy
- B. Radiant energy
- C. Solar energy
- D. Kinetic energy
Explanation
Heat energy increases the kinetic energy of molecules, causing them to move faster and collide more effectively, thereby activating a chemical reaction.

About Enzymes
Enzymes are biological catalysts that lower activation energy without being consumed, and their specificity is explained by the lock and key and induced fit models. Work includes the effects of temperature, pH and substrate concentration on reaction rate, plus competitive and non-competitive inhibition and how these differ.
