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

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?
