Course Title: Honors Chemistry Unit: Equilibrium Glenbard District 87 Unit Title: Stage 1 – Desired Results Established Goal(s): What relevant goals (e.g. Content standards, course or program objectives, learning outcomes, etc.) will this address? 1. Students will be able to explain the concept of chemical equilibrium and use it to make predictions. (IL Learning Standard:
12.C.5a)
2. Students will be able to use Le Chatelier’s Principle to determine the response of a system when a stress is applied. (IL Learning
Standards: 12.C.4a and 12.C.5a)
Understanding(s): Students will understand that… 1. Equilibrium exists when the rate of a forward reaction is equal to the rate of the reverse reaction. 2. When a stress is applied to a system at equilibrium, the system will react in a way to relieve that stress and reestablish equilibrium. Knowledge: Students will know… 1. How equilibrium can be established in reactions. 2. The factors that disturb equilibrium. Essential Question(s): What provocative questions will foster inquiry, understanding, and transfer of learning? 1. What is meant by “equilibrium”? 2. How does a chemical system relieve stress? Skills:Students will be able to … 1. Write an equilibrium expression. 2. Calculate an equilibrium constant. 3. Explain how to determine whether a chemical reaction favors reactants or products using the equilibrium constant. 4. Perform ICE calculations to determine equilibrium constant. 5. Calculate Keq or Ksp values. 6. State Le Chatelier’s Principle and explain its meaning. 7. Use Le Chatelier’s Principle to determine the shift that will occur when a stress is applied to a system at equilibrium.
