SCH4U - Chemistry 12 (2024-25) - A

SCH4U – Lesson Plan 4-1

Chemical Equilibrium

Lesson Big Idea:

Chemical reactions are dynamic events, occurring both forwards and backwards until a balancing point is reached.  This balancing point is called equilibrium and is affected by different factors including concentration and the equilibrium constant.

Ministry Expectations:

E2.1

E2.2

E3.1

E3.2

E3.3

Learning Goals:

• Define dynamic equilibrium.
• Explain the concept of chemical equilibrium.
• Describe Le Chatelier's principle and apply it to solve problems predicting how changing variables will affect the chemical equilibrium of a system.

Success Criteria:

I know I have achieved the goals for this lesson when I can describe dynamic equilibrium and explain how it relates to chemical reactions.  I will also be able to explain Le Chatelier's principle and use it to predict the direction of reactions when different variables such as temperature and concentration are changed.
