Question 1
Which statement best describes heterogeneous catalysis?
- Reactions occur in the same phase as the catalyst.
- Reactions occur at the interface of different phases.
- Reactions only involve liquids.
💡 Hint: Think about how phases interact in catalysis.
Question 2
True or False: The rate-determining step is always the first step in a reaction mechanism.
- True
- False
💡 Hint: Remember, it's about speed, not order.

Challenge Problems
Push your limits with challenges.
Question 1
If the adsorption constants K_A and K_B have values of 0.5 and 0.2 respectively, calculate the rate of reaction if the partial pressures of A and B are both 1 atm.
💡 Hint: You'll need to organize your rate law into a form where k can be evaluated or known.
Question 2
Discuss how increasing the catalyst's surface area could improve reaction rates in the Haber-Bosch process. Include examples.
💡 Hint: Look at how collisions and availability of sites intersect.
