Challenge Problems

Push your limits with advanced challenges

Challenge 1 Hard

Given the reaction: A + B -> C, with a proposed mechanism containing a rate-determining step of A + B -> D, then D -> C. How would you express the overall rate?

💡 Hint: Concentrate on what the RDS contains.

Challenge 2 Hard

If the addition of a catalyst alters the mechanism of a reaction, what effect does this have on the rate law, if any?

💡 Hint: Think about the roles of catalysts and how they affect pathways.
