Question 1
What is the rate-determining step?
- The fastest step in the mechanism
- The step that limits the overall reaction rate
- The first step of the reaction
💡 Hint: Consider which step controls the pace of the entire process.
Question 2
True or False: Intermediates appear in the overall balanced equation.
- True
- False
💡 Hint: Think about the lifecycle of intermediates in the reaction.

Challenge Problems
Push your limits with challenges.
Question 1
Consider a reaction where A + B → C occurs in two steps: Step 1 is A + B → D (slow) and Step 2 is D → C (fast). Write the rate expression and explain why the first step is rate-determining.
💡 Hint: Focus on the rate of the first step and how it influences the overall reaction.
Question 2
A proposed mechanism for a reaction is: Step 1 (fast): A + B ↔ C (intermediate), Step 2 (slow): C + D → E. Derive the overall rate expression and give reasons for the steps identified.
💡 Hint: Remember that the RDS determines how we express the rate.
