Day 8 - Thursday, April 23
to Day 8 of eLearning. The goal is to deepen our understanding of
reaction rates and the Collision Model. There is a YouTube video to
help you with the instructional component. And there is a Concept
Builder to ensure that you comprehend. Finally, if you didn't do it on
Monday, there is a Method of Initial Rates video and accompanying
Here's What to Do:
- Collsion Model (15 minutes)
H discusses the Reading Guide on Reaction Rates and the Collision
Model. He does so with an eye for getting you through the Concept
Builder parts. If you would like to grab a copy of the Reading Guide
answer key, see the link below.

- Collision Model Concept Builder (20-35 minutes)
Go to www.physicsclassroom.com/account
- Log into your account. Go to the Tasks and Courses page.
- Click the link to the Collision Model Concept Builder.
- Do all three activities.
|Pro TIP: The Help Me! button of every question screen opens a page with information specific to the question. Focus on the How to Think About This Situation section of the Help page. Most of the time it is very detailed to the point of telling your the answer.
- Method of Initial Rates - Video + WebAssign (20 min - 30 min)
(You may have already done Activity 3; it was an option on Monday's Lesson.)
reaction rates allow chemists and chemical engineers to control it.
Sometimes you want a reaction rate to occur fast - like for the
production of a product that you are going to sell by the ton.
Sometimes you want a reaction rate to occur slow - like the rusting of
the body of that Dodge Ram pick-up truck. And other times, you just
want to simpy be able to exercise exquisite control of the rate - like
the biochemical reaction of the ADHD medicine in the bloodstream of a
child. So how do Chemists study and understand reaction rate? We are
going to find out. Watch Mr. H's short video and do the accompanying
