Question 1

What defines the rate-determining step in a multi-step reaction?

  • The fastest step
  • The slowest step
  • Any single step

💡 Hint: Think about which step would create the biggest delay.

Question 2

True or False: All steps in a reaction contribute equally to the overall reaction rate.

  • True
  • False

💡 Hint: Consider which step might control the timing.

Challenge Problems

Push your limits with challenges.

Question 1

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!

Question 2

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.
