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 advanced challenges

Challenge 1 Hard

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.

Challenge 2 Hard

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.
