Acid & Base ReviewEquilibrium Notes & Lab
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
Lesson Sequence
•Evaluate: Warm – Up•Explain: Equilibrium Notes•Engage, Explore Elaborate: Equilibrium
Lab•Evaluate: Exit Ticket
Warm - Up
•Given the salt KCl was a product of a neutralization reaction, predict what reactants were used to produce the salt

equilibrium Model the process of chemical equilibrium by
completing a lab

Equilibrium Notes
Brainstorm: What does it mean to be in equilibrium?
Chemical Reactions
•We are use to thinking about chemical reactions like this:
Chemical Reactions can be Reversible•Some reactions are reversible, where the
products can regenerate the original reactants
Chemical Equilibrium
•The forward and reverse reaction rates are equal
•Equilibrium DOES NOT mean the concentrations of reactants and products are equal
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
Equilibrium LabComplete the lab activity in class. If you do not finish the questions in class, they will become homework
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.
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.
