Challenge Problems

Push your limits with advanced challenges

Challenge 1 Hard

Describe the implications of the rate-determining step in industrial chemical processes. How would you optimize a reaction based on this understanding?

💡 Hint: Consider how improving flow could enhance production!

Challenge 2 Hard

Given a reaction A + 2B → C with an unknown rate law, if increasing [A] doubles the rate, while increasing [B] quadruples it, identify the order of the reaction concerning A and B.

💡 Hint: Think about how each change in concentration relates to the observed rate change.
