Spent first half of class reviewing gas laws and working on AP problems. 2nd half you worked on lab write-ups.
Because almost all groups had to work through some rather complicated calculations to detemine partial pressure, we spent all class doing the lab calculations.
Notes on Kinetics – collision theory, did Boltzmann Buck Rock Paper Scissors demo and did Boltzmann worksheet. Also went over potential energy diagrams, including activated complex.
HW: Effusion/Diffusion reading and questions + work on lab write-up
Today we reviewed collision theory and the Boltzmann Distribution. I did some demos and went over the four factors that affect reaction rates and then you had some time to answer the following questions that were submitted for feedback:
- Why does temperature affect reaction rate? Refer explicitly to collision theory and the Boltzmann distribution.
- Why do catalysts affect reaction rate? Refer explicitly to collision theory and the Boltzmann distribution.
The second half of class we did ChemActivity 36 (in packet it comes after the effusion/diffusion assignment and after the catalyst article) that teaches you how to calculate reaction rate. We skipped the activity on reaction rate graphs 17 but did do the Potential energy diagram worksheet. The last 15 minutes of class I handed back your redox test and went over some of the commonly missed questions.
HW: finish lab write-up and catalytic convertor article and questions
