  1. Acid & Base ReviewEquilibrium Notes & Lab

  2. Objective: • Today I will be able to: • Explain how reversible reactions reach equilibrium • Model the process of chemical equilibrium by completing a lab • Evaluation/Assessment: • Informal assessment: Monitoring student interactions as they complete the review and the lab activity • Formal assessment: Analyzing student responses to the lab, practice and the exit ticket • Common Core Connection • Build Strong Content Knowledge • Reason abstractly and quantitatively • Use appropriate tools strategically

  3. Lesson Sequence • Evaluate: Warm – Up • Explain: Equilibrium Notes • Engage, Explore Elaborate: Equilibrium Lab • Evaluate: Exit Ticket

  4. Warm - Up • Given the salt KCl was a product of a neutralization reaction, predict what reactants were used to produce the salt

  5. Objective • Today I will be able to: • Explain how reversible reactions reach equilibrium • Model the process of chemical equilibrium by completing a lab

  6. Homework • Acid and Bases Exam • Thursday, May 15 • Finish Equilibrium Lab Questions

  7. Agenda • Warm – Up • Equilibrium Notes • Equilibrium Lab • Exit Ticket

  8. Equilibrium Notes

  9. Brainstorm: What does it mean to be in equilibrium?

  10. Chemical Reactions • We are use to thinking about chemical reactions like this:

  11. Chemical Reactions can be Reversible • Some reactions are reversible, where the products can regenerate the original reactants

  12. Chemical Equilibrium • The forward and reverse reaction rates are equal • Equilibrium DOES NOT mean the concentrations of reactants and products are equal

  13. Dynamic Chemical Equilibrium • Chemists refer to equilibrium as dynamic because the reaction does not stop when it reaches equilibrium, but becomes constant • The system is changing but there is no net reaction • In a closed system, almost all reactions will reach equilibrium

  14. Equilibrium Lab Complete the lab activity in class. If you do not finish the questions in class, they will become homework

  15. Equilibrium Lab Directions • Watch Ms. Ose’s Demo • Do NOT throw the beans or you will complete an alternate activity • When you finish with the beans answer the questions.

  16. Exit Ticket • If a reaction begins with a different quantity of reactant and product, can equilibrium still be reached. Explain based on what you saw in the Equilibrium lab.
