SCH 4U1 UNIT PLAN
UNIT 3: Chemical Systems & Equilibrium
Chapters 7-8
LEARNING GOALS FOR THE UNIT
 Demonstrate an understanding of dynamic equilibrium in a variety of situations, and
use the equilibrium law to solve problems
 Apply Le Chatelier’s principle to predict how various factors affect a chemical
system at equilibrium
 Carry out laboratory investigations to explore equilibrium systems and to determine
equilibrium constants
 Explain how equilibrium principles may be applied to optimize the production of
industrial chemicals
 Identify the effects of solubility on biological systems
