Study for the summative assessment on chapter 18 on Reaction Rates and Equilibrium that is to be given on your next school day that our class meets. Today is day 153. Study for your test which is scheduled for school day 154! If your class does not meet on day 154, today’s home learning activities are listed under day 154 and on day 154 your home learning activities are those listed below.
Start the following in class:
1.a. Go to http://www.phschool.com/webcodes10/index.cfm?fuseaction=home.gotoWebCodewcprefix=cdawcsuffix=1180 and take an online formative test for chapter 18, Reactions Rates and Equilibrium.
- Then click on the Score My Test button and study anything that you do not yet understand.
- Review and study your notes, and your journal reflections. Study your learning log, your Cornell Notes, and anything that was misunderstood on the Chapter 18 Study Guides, Chapter 18 Section Reviews, Chapter 18 Reaction Rates and Equilibrium[Formative] Test A, and other work sheets which you now have checked using green ink.
1.b. Examine this chapter’s learning objectives, one by one.
- Are you able to demonstrate your understanding or mastery of each of this chapter’s learning objectives?
- How do you know you can?
- What has formative assessment of each objective informed you about?
1.c. Continue studying for the chapter 18 summative assessment on Reaction Rates and Equilibrium. Understand about and be able to do the following.
1) Explain the answer to each chapter 18 ActivInspire flipchart learning question that you were asked to think about.
2) Express a reaction rate as a change in concentration of a reactant being used up or a change in concentration of a product being produced per unit time.
3) Describe the effect of
- changing a reactant or product concentration,
- changing the temperature of the reaction mixture, and
- adding a catalyst or
- poisoning a catalyst
on the rates of the forward and reverse reactions.
4) Describe the concepts of
- reversible reaction,
- incomplete reaction,
- forcing a reaction to go to completion.
5) Distinguish a non-equilibrium state of a chemical system from an equilibrium state of that system.
6) Write an equilibrium constant expression for a chemical system whose chemical equation is known.
7) Determine the equilibrium constant for a given system at equilibrium.
8) Solve problems involving a given equilibrium constant and all but one of the equilibrium concentrations of the chemical species present at equilibrium.
9) Write equations for the dissociation of named ionic solutes dissolving in water.
10) Find the value of a solubility constant using data gathered from the making of a saturated solution of the substance.
11) Solve problems using a given solubility product constant.
12) Compare and contrast the way a catalyst behaves in a chemical reaction to the way a reaction intermediate behaves.
13) Write a rate law, given data on how the initial rate of reaction varies as the initial concentration of each species is varied.
14 ) Review Figure 18.3 on page 542, Figure 18.4 on page 543, Figure 18.5 on page 543, Figure 18.8 on page 547, Figure 18.9 on page 549, Figure 18.10 on page 550, problems I18-6 on page 555, I18-7 on page 556, Table 18-2 on page 562, I18-17 on page 562, I18-19 on page 564, Figure 18.24 on page 570, Figure 18.25 on page 572, Figure 18.27 on page 576, Figure 18.28 on page 578, and the relationship that G = H – (T · S).
15) Make sure that you can correctly do and show your work for each type of chapter 18 problem presented in the text, the worksheets, formative assessments, or in class.
16) On page 580 of the text review the Key Concepts for each text section and clarify in your mind under what circumstances would it be helpful to use each of the different relationships shown in the Key Equations section.
Recommended for those who have time left in their 45 minute study period, but not required of all:
1. Read and study the Study Guides given on pages 33, 57, 95, 121, 148, 180, 206, 246, 280, 314, 346, 378, 406, 438, 464, 498, 534, and 580 of the text.
2. Review those concepts that we have discussed in class that are in your study guides, that are in your text study guide at the end of the chapter, and that on the chapter vocabulary sheet provided to you that describes what is a substance, an element, a compound, a coarse mixture, a colloidal suspension, a solution; an atom; a formula unit, a molecule; a phase, an aqueous phase; a chemical change, a physical change; a chemical reaction, a reactant, a product, a word equation, and a formula unit equation. How are these concepts different? You need to be able to explain the meaning of each of these terms, and be able to differentiate the terms, be able to compare and contrast these related terms, and give examples that make clear the points that you are trying to explain. Go over each of these concepts with your study partner.
3. Review the SI prefixes and their meanings until you can readily explain the meaning of each listed SI prefix as a numerical multiplier.
