Framework for Teachable Unit
Topic: Equilibrium
Group Members’ Names: Brandi , Randy, Casey Jones, Matt and Teresa Brooks
Learning Goal:
1) Understand the relationship between kinetics and equilibrium
• Describe the rate law expression from an elementary step
• Generate an eq’m constant expression from rate law expressions
• Relate the ratio of individual rate constants to Keq and concentration of Reactants and
Products
• Predict the shift in equilibrium with change in conc’n or temp
• Choose a rxn coordinate graph given that a reaction favours products under certain
condition
• Interpret graph of concentration versus time to understand ratio of k1/k-1
• Compare/Contrast conc’n vs time graphs
Summative Assessments (describe how you would assess your objectives and paste in any
summative assessments you have created):
1) Draw the conc’n vs time graph for an equilibrium reaction in which k1 = x and k-1 = y
2) Given the Keq = , sketch a conc’n vs time graph that describes the equilibrium reaction of
A -> B
Formative Assessments (activities/instruction you designed to teach the learner; please
describe your instructional methods referring your PowerPoint presentation so that others
could give this presentation at their own institution.)
1) Use beakers with blue and red dots to demonstrate the inevitability of equilibrium
Consider the reversible reaction of A <-> B which is called an equilibrium reaction we are
going to model this reaction with dice
You are all molecules of A, each time the dice are rolled if you get 1-5 sit down (click A) or
stay seated, if you roll a 6 stand up or stay standing (click B)
Start with everyone sitting do activity 10 times
What trend do you see?
Then start with everyone standing and repeat
Do you think the result will be the same?
2) Show a couple different conc’n vs time graphs, what do they have in common?
1) After looking at rate diagrams, what do you notice?
2) Why do the concentrations flatten out?
