Answers
to Math Quiz (not to be handed in) This quiz
illustrates the level of math that we will use in Chem 102.
Bonus Opportunity
Problems (BOPs)
Note: I'm primarily assigning odd problems.
The answers are in the back of the textbook and worked out in the
solution manual if you are having problems.
The solution manual is included with OWL. They are meant to
be a little more challenging
than OWL and a bit closer to exam problems. Like the OWLs,
problems are due on the Thursday after each exam.
BE SURE YOU SHOW ALL WORK FOR CALCULATIONAL PROBLEMS!
IF YOU GIVE JUST THE ANSWER, YOU WILL GET A 1 FOR THE ENTIRE ASSIGNMENT.
YOU ARE WELCOME TO USE THE E-SOLUTION MANUAL LOCATED IN OWL. THE LINK IS RIGHT BELOW THE E-BOOK LINK.
| BOPs | Assignments (Show all work for calculations) |
| Set 1 | Chepter
14 (p648) - 1, 13, 17, 29, 33, 41, 45, 47, 65 (for bp, see
Table 14.3), 69 Chapter 5 (p239) - 45, 51, 57, 61 Chapter 19 (p886) - 1, 5, 7, 9 (and this is it!) |
| Set 2 | Chapter 19
(p886)
- 15, 19, 25, 53 (omit (c)) Notes: Product-favored means the reaction is spontaneous in the forward direction. Reactant-favored means the reaction is non-spontaneous in the forward direction, and spontaneous in the reverse direction. Entropy-driven means that the reason why the forward reaction is spontaneous is because of the TdeltaS term in Gibbs-Helm. Eq. Enthalpy-driven means that the reason why the forward reaction is spontaneous is because of the delta H term in Gibbs-Helm. Eq. Chapter 15 (p708) - 1, 3, 7, 9, 11, 15, 17, 29, 37, 39, 41, 45 (add (c): what is the overal rate law expression? add (d) what is the overall rate law expression if Step 1 was the slow step? ), 53, 100 (Extra Question): Explain how a catalyst works. Include the answers to: Does the catalyst participate in the reaction? Does the catalyst change the mechanism? Does it change delta E in reaction? Does it change the activation energy? Chapter 16 (p748) - 1 (for gases, use concentration), 5, 9, 13, 19, 21, 25, 27, 29, 33, 39 Extra question: Consider the gas phase reaction A + B <--> 2C. with Kc = 81 at 30oC. What is the final concentration of B if you start with only 3.0 M of C in the container? (This is it!!) |
| Set 3 |
Chapter 16 (p748) - 43 Chapter 19 (p886) - 27, 51 Chapter 17 (p797) - 3, 9, 13, 15, 31, 45, 47, 49, 51, 57, 59, 61, 63, 77, 84 Chapter 18 (BUFFERS) (p848): 3, 5, 7, 9, 11, 79, 19, 21, 23, 25, 29, 30 (answers: (assuming 5% rule): (a) 5.35 (b) 9.40 (c) change to pH after adding 12.0 mL of NaOH: pH= 9.81 (d) 16.7 mL (e) 10.94 (f) Alizarin yellow (g) change to pH after 18.0 mL of base is added: pH = 11.37. |
| Set 4 | Chapter 18 (SOLUBILITY PRODUCTS): 37, 41, 43, 47, 51, 55, 61, 63, 73 Chapter 20 (p937): 3, 5, 7, 9, 13, 17, 19, 25, 27, 31, 33, 37, 41, 43, 45, 55 (that's it for the semester) |
