Midterm Review

We went over commonly missed problems on the midterm and reviewed equilibrium.

There is a test next time.

Homework:
Chapter 13 AP Review Questions

Answers: 1. A; 2. C; 3. B; 4. C; 5. D; 6. B; 7. A. 8. D; 9. A; 10. C; 11. C; 12. B; 13. B; 14. D; 15. D; 16. D

End of Equilibrium Chapter

But I have been convinced to save the exam until next Wednesday (because we were missing two people in class today).

So, we will review a bit on Monday and maybe go over the midterm.

Homework:
  Study appropriately

Equilibrium Again

Equilibrium is not all that hard.  We will fly through the material and the test will be either Monday or Wednesday.

Things to remember:

1. Equilibrium occurs when forward rate = reverse rate
2. Pure solids and liquids don't count.
3. Q = reaction quotient.  Same as equilibrium constant, but with initial concentrations.

Equilibrium (except not really)

Okay, okay.  So it may have been a bad idea to start equilibrium this quarter.  I just really, really wanted to be totally done before Q4 started.

Oh, well.  Forget it.  We'll just practice for the midterm next week.  Especially combining things that we have learned in our 8 units so far.


Homework:
  2013 AP Chemistry Exam FRQ (#3 & #5)

Unit 7 Exam

The test went well today.  Everyone made at least a B.  Good job!

On to equilibrium.

Tomorrow's lab is in the labs folder.

Homework:
  Read Chapter 13 (I think.  The one on equilibrium).  Answer the review questions at the end.

Finishing Up Kinetics

We finished up just a few things:

1. Activation energy represents the energy necessary to form a transitional state.
2. Catalysts speed up reactions by making it easier for transitional states to form.

There is an exam next time.

Homework:

Kinetics

We didn't do a lot in class due to the Grandparent's Day Mass.
