STAGE I – DESIRED RESULTS
LESSON TOPIC: Acid – Base Equilibria
BIG IDEAS: (Content standards, assessment anchors, eligible content) objectives, and skill focus)


Changes in matter are accompanied by changes in energy.
Chemical reactions are predictable.
ESSENTIAL QUESTIONS:


How are changes in matter accompanied by changes in energy?
How do stoichiometric ratios relate reactants to products in a chemical reaction?
UNDERSTANDING GOALS (CONCEPTS): Students will understand:

A chemical reaction will proceed until equilibrium is reached or until a limiting reactant is exhausted.
VOCABULARY: chemical equilibrium, heterogeneous equilibrium, reaction quotient, physical equilibrium,
homogeneous equilibrium, equilibrium position, dynamic equilibrium, law of mass action, Le Chatelier's
principle, static equilibrium, equilibrium constant
STUDENT OBJECTIVES (COMPETENCIES/OUTCOMES): Students will be able to
