Question 1

What happens to reaction rates when the concentration of reactants increases?

  • They decrease
  • They stay the same
  • They increase

💡 Hint: Consider the more people you have in a room, the more conversations can happen.

Question 2

True or False: Catalysts increase the activation energy required for a reaction to occur.

  • True
  • False

💡 Hint: C is for Catalyst, and C is for lower your costs!

Challenge Problems

Push your limits with challenges.

Question 1

If you were to increase the concentration of both A and B in a double displacement reaction, predict how this would affect the rate and justify your reasoning using collision theory.

💡 Hint: Think about how many dancers are on the dance floor, the more there are, the more collisions occur!

Question 2

Design an experiment to test the effect of catalyst presence on the rate of a specific reaction. How would you set it up, and what measurements would you take?

💡 Hint: What will you track in the reactions to measure rates?
