Module 7—Principles of Chemical Equilibrium

Reflect on the Big Picture

 

In this lesson you have examined some chemical systems, and you have learned about the criteria that define an equilibrium system. In the remaining Module 7 lessons you will investigate more chemical systems and other aspects of equilibrium.

 

Create a table to summarize what you have learned about the systems so far. You will add to this table throughout Module 7, and you will use your table for the Module Assessment.

 

Procedure

 

RBP 1. Create a table like the following:

 

System	Open or Closed?	Observation of Macroscopic Changes?	Observation of Microscopic Changes?
Cabin and Friends
HCl(aq) + Mg(s)
Methylene Blue, Glucose, Potassium Hydroxide, and Oxygen

 

RBP 2. Fill in the table with the systems you investigated in this lesson and your observations for each system.

 

Reflect and Connect

 

RC 1. Take some time as you go through your day to note systems in your life that are examples of either static or dynamic equilibrium. Choose the best examples and describe why each one meets the criteria for a system at equilibrium. Summarize your examples on your table of equilibrium systems.

 

Post your examples of systems at equilibirum to the discussion area for your class. Review the postings of at least two other students. Provide feedback to help the students improve the precision of their examples. Revise your examples using feedback you receive from other students. Save your revised examples in your course folder.
