Day 7 - Monday, April 20

Welcome to Day 7 of eLearning. Today is the first lesson of several lessons on Unit 8 - Kinetics and Equilibrium. We start with the topic of Kinetics - the study of the rates at which reactions occur.

NOTICE: Packet pages are available online. They can be printed as needed. You would not have any of the pages below since we started this unit after the quarantine started.

Here's What to Do:

NOTICE: Today is probably a "light" day. The next class is significantly heavier. One of the activities next class involves using the Method of Initial Rates Video to do a WebAssign. I've listed that item as #3 in today's plan for those who like to get a head start on the Day 8 Lesson. Doing #3 today makes the Day 8 Lesson the "light" day. Item #3 involves a video and accompanying WebAssign.

  1. Reaction Rates Simulation    (15 min - 30 min)

    The rate of a reaction refers to the rate at which products are produced. In this activity, you will examine four variables to see if they affect and how they affect the rate of a reaction. The activity is a simulation; the link is below. Begin by going to Google Classroom to get your copy of the activity. Complete the activity and hand it in on Google Classroom.


  2. Reading on Reaction Rates    (20 min - 45 min)

    Read Chapter 17.1-2 of your textbook and complete the accompanying WebAssign Reading Guide.

  3. Method of Initial Rates - Video + WebAssign     (20 min - 30 min)

    (Before you begin ... see the NOTICE above about Activity 3.) Understanding 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 WebAssign.
