Challenge Problems

Push your limits with advanced challenges

Challenge 1 Hard

Using the Arrhenius equation, calculate the rate constant k if the activation energy is 50 kJ/mol at a temperature of 300 K.

💡 Hint: Remember to use the gas constant R in proper units.

Challenge 2 Hard

Design an experiment to compare the reaction rates of a catalyzed vs. uncatalyzed reaction. Outline your procedure and discuss the expected outcomes.

💡 Hint: What measurements would best demonstrate the difference in rates?
