Question 11 11. What is the frequency factor?

Question 12 12. 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 13 13. What does the m stand for in the rate law equation?

Question 14 14. 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?
