In this module, you will learn about many chemical systems demonstrate the principles of systems at equilibrium. You will learn how equilibrium can be classified, studied, and manipulated. You will study the chemical principles used to predict equilibrium changes in a system under stress and learn about how catalysts affect chemical equilibria.

In Module 7, you will consider the following overarching questions:

• What is happening in a chemical system at equilibrium?
  
  
• How do scientists predict shifts in the equilibrium of a system?
  
  

Module 7 contains four lessons:

Lesson 1

Explaining Chemical Equilibrium Systems

Lesson 2

Quantifying Chemical Equilibrium Systems

Lesson 3

Le Chatelier's Principle

Lesson 4

Catalysts and Chemical Equilibrium Systems
