Challenge Problems

Push your limits with challenges.

Question 1

A reaction has an activation energy of 50 kJ/mol. If the temperature is increased from 300 K to 400 K, what effect would you expect on the reaction rate and why?

💡 Hint: Think about how temperature affects particle kinetic energy.

Question 2

Give an example of a situation in baking where increasing surface area leads to a faster reaction rate and explain how it works.

💡 Hint: Consider how smaller pieces compared to whole items change reactivity.
