Question 1 1. Why is a collision between molecules usually necessary for a reaction to take place?

Question 2 2. 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 3 3. In the rate law (Rate = k x A), what does the A stand for?

Question 4 4. If the exponential factor is close to 1, what is known about the activation energy and temperature?

Question 5 5. What molecule in our bodies is a catalyst?

Question 6 6. What is the frequency factor?

Question 7 7. What is a catalyst?

Question 8 8. What does the m stand for in the rate law equation?

Question 9 9. What does the k stand for in the rate law equation?

Question 10 10. What does an increase in temperature do the reaction rate?

Question 11 11. 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 12 12. What is the rate-determining step?

Question 13 13. What is the Arrhenius equation?

Question 14 14. 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 16 16. In the reaction A = B, if the rate quadruples for every doubling of A, then what is the reaction order?

Question 17 17. 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 18 18. What is an activated complex?

Question 19 19. How might the exponential factor equal one?

Question 20 20. What are intermediates?

Question 21 21. How is increased pressure related to reaction rates?

Question 22 22. If we know that manganese dioxide is a catalyst in the decomposition of hydrogen peroxide, then how does manganese dioxide affect this reaction?

Question 23 23. What is the rate law?

Question 24 24. How is reaction rate measured?
