Question 11 11. Suppose you were teaching a science class to middle school students. Because you want to show them an impressive chemical reaction, you decide to dissolve zinc in hydrochloric acid. You add more acid than usual and throw in pieces of zinc. What factor is not going to impact the reaction rate?

Question 12 12. If a chemical reaction has an activation energy of 500 J, and its reactants are assembled with 250 J of energy, what will happen? Why?

Question 13 13. How is reaction rate measured?

Question 14 14. What is the rate law?

Question 15 15. How does an increase in temperature affect the rate of a reaction?

Question 16 16. What is the frequency factor?

Question 17 17. What is the rate-determining step?

Question 18 18. If the exponential factor is close to 1, what is known about the activation energy and temperature?

Question 19 19. What molecule in our bodies is a catalyst?

Question 20 20. What does the m stand for in the rate law equation?

Question 21 21. If a scientist induces a chemical reaction, and finds that the reactants and products exist in a single phase, then what did the scientist observe?

Question 22 22. What is an activated complex?

Question 23 23. If a scientist is trying to determine the reaction order for a given reaction, then what's the most effective means to figure it out?

Question 24 24. What does an increase in temperature do to the reaction rate?

Question 25 25. What makes the statement 'the presence of a catalyst will slow down a reaction' incorrect?
