Weds, Jan 12, 2022
Announcements
- 0) Nearly all of you in PChem II are also in PChem I. There are some introductory topics that I want to share with all PChem students, so there is some duplication of assignments at the beginning of Chem 312 and 322. Only complete items below that are new to you.
- 1) If you have not done so, please review the syllabus linked here.
- 2) Question: Is your computer up to speed? During this course, we will be using software such as Excel, WORD, Igor, Mathematica etc. Although there are computers available on campus (specifically in CSB 373), it is most convenient for you to install this software on your computer (laptop preferred). It may be the case that a "ChromeBook" or other cloud-based OS device may have sufficed in the past, it will not work in PChem...but computers will be available in CSB 373. Please see/email me with any questions.
Class Assignments
- 1) I would like for you to watch the following video that discusses being proactive vs. reactive. I have found that PChem students who are most successful would describe themselves as being proactive. I think you will agree that we should all shoot for being proactive in our lives, but this is a clear skill that even I am working on improving. The video moves quickly, so I suggest you just listen the first time, then consider coming back to this view it again at another time. We will discuss this more in class when we meet in person.
- Proactive vs. Reactive
- 2) If the above material is interesting, consider learning more about Stephen Covey or how to use the Franklin Planner.
...now on to PChem...
- 3) It is time to start reading the text. Please note, that reading any science textbook is NOT like reading other documents. The information is presented in a very dense way...this means that there is a lot of scientific language that needs to be read multiple times in order to make sense. The Quantum textbook (Chem 322) is more clearly written than the Thermodynamic textbook (Chem 312). The authors, Engel and Reid initially published a single textbook containing both sections called "Physical Chemistry" (literally the two books bound into one). In addition to the single textbook, the publisher always printed the two sections separately; the 4th edition of this textbook is only printed as separate sections...no more single textbook containing both. As you will note, the Quantum textbook is written by Engel alone. I meet this author and had lunch with him at the 2017 Denver ACS meeting: great guy, has essentially retired and works mainly on gardening and editing his textbooks.
- - Let's start by reviewing the MATH ESSENTIALS 1 section (Page 1-3). As you might already know, PChem uses the language of mathematics to organize its contents. Calc 1 and Calc 2 are prerequisites for this course (although they are sometimes waived). Yes we will be taking derivatives and integrals, but more importantly, you need to be comfortable with math in general. Math is a tool and by the way, you cannot hate a tool, as in..."i just don't like hammers." Although you may have had a bad experience with math in the past, i will present math in a way that you will find it helpful...like how a hammer is really good at driving nails!
- Please review this section (pages 1-3) now. In your notes, please write down all of the units listed in Table ME1.2 and indicate whether you are comfortable with these units (check) or not (???).
- In Section ME1.2...sig figs...this is something you should know well!
- In section ME1.3...they suggest that writing out all of your work is strongly suggested since it allows you to go back and correct any errors. Please work this problem in your notes as if you were going to answer this question on an exam (ie. Show your work). Now use Excel to reproduce the spreadsheet shown at the bottom of page 3. At a later time we will use Mathematica to solve such problems.

- - The next pages in the textbook are an additional 3 MATH ESSENTIALS sections (2-4). These will be VERY handy in the future as a place to look up derivatives and integrals, but for now let's skip these sections.
- - The first Chapter of the textbook makes a strong case related to why we need quantum mechanics and not just classical mechanics. There are 4 experiments done in modern times (last 100 years) that have shown that classical mechanics cannot explain the experimental outcomes, the experiments are named:
- 1) Blackbody Radiation (Sec 1.3)
- 2) The Photoelectric Effect (Sec 1.4)
- 3) Particle-Wave Duality
- - Particles acting as waves (Sec 1.5)
- - Waves acting at particles (Sec 1.6)
- 4) Emission Spectra (Sec 1.7)

- For now, i would like for you to read Sec 1.1 and 1.2, but get ready to do some math shortly.
