Challenge Problems

Push your limits with challenges.

Question 1

A reaction between hydrogen and oxygen to form water requires specific conditions to proceed. If a catalyst is added to the reaction, explain how this impacts the activation energy and the rate of the reaction. Provide a detailed comparison with the original reaction without the catalyst.

💡 Hint: Think about how catalysts change the energy barrier for reactions.

Question 2

You are studying the decomposition of hydrogen peroxide. Explain how adjusting the temperature impacts the rates of reaction and describe in detail using collision theory.

💡 Hint: How do temperature changes relate to particle motion and collisions?
