Chemistry Unit 2 Day 2

Learning Objective: Students will learn about factors that affect reaction rate by doing and a lab and will hypothesize, analyze and interpret data in writing using technical vocabulary: concentration, temperature, pressure, collision theory, kinetic energy, molecules, chemical reaction.

Questions:

1. How can you make a reaction speed up? (book or brain)
2. How does collision theory make chemical reactions happen?
3. What most likely accounts for the difference between curve A and curve B on the energy diagram

4. Answer choices for #3:

   A. The reaction described by curve B is at a different temperature. B. The reaction described by curve B is under greater pressure. C. The reaction described by curve B has higher reactant concentrations. D. The reaction described by curve B is occurring with a catalyst. Exit Ticket for Day 2:  Suppose you had to explain collision theory and reaction rates to a friend, what would you tell them? What would be the most difficult part for you to explain?
