Challenge Problems

Push your limits with challenges.

Question 1

A student is conducting an experiment to demonstrate the effect of a catalyst on the decomposition of hydrogen peroxide. The reaction with that catalyst was completed in half the time of the uncatalyzed reaction. Calculate the rate enhancement and discuss its significance.

💡 Hint: Consider comparing both reactions' completion times.

Question 2

Evaluate the effect of catalyst in a hypothetical reaction where the equilibrium constant is 10^-10 and a catalyst is introduced. Discuss how this might impact product yield over time.

💡 Hint: Focus on the definition of equilibrium constant.
