Week of 11/18 to Thanksgiving

A copy of my typed, somewhat organized Equilibrium Notes!

Monday: ICE Tables!  Equilibrium SMART Board notes on solving for equilibrium composition given K.  Use of quadratic formula (or wolfram alpha! or your solvers).  Near end of class introduced idea of Q, reaction quotient and how to interpret to determine if reaction in proceeding in forward or reverse direction.

Tuesday: Warm-up question on interpreting magnitude of K, then a problem in which reactant was added and solve for a new composition at equilibrium to illustrate the point that K stays constant but amounts of reactant and product can change.  Then started notes on LeChatelier’s principle and did the Le Chatelier’s ship.  Have not gone over exothermic/endothermic or special pressure or catalyst yet.  (Notes)

Wednesday: Rest of LeChatelier’s principle.  Use this animation to show what is happening.  This worksheet for practice and do an Exploration Lab.

Thursday: How to increase percent yield using LeChatelier’s principle, Kp and some practice worksheets interpreting equilibrium graphs.

Friday: Work day, handed out practice test so I went over some of the questions.

Monday: Equilibrium Test

Tuesday: Canceled b/c of Turkey bowl. T-bowl was cancelled, but I cancelled class anyway.

Week of 11/11

Monday: Veteran’s Day, no school

Tuesday: Went over practice test questions

Wednesday: Kinetics Test

Thursday:  Reversible Reactions Simulation. Then Oscillating reactions demo and Notes on Equilibrium Constant with CA 39

Friday: More on equilibrium constant with CA 39. (Note to self, see notebook paper in binder has what problems to do). Specifically went over how to handle K’s for reversed reactions, reactions multiplied by a coefficient, etc.

Week of 11/4

Monday: First part of class was a review of all we’d learned so far.  Second half we did Ea worksheet.

Tuesday: Teacher work day

Wednesday: We went over how to calculate rate and determine rate laws.  Then I did some demos in preparation for you to design a lab to determine activation energy.  The iodine clock went over well and you all wanted to do iodine clock.  (Demos done: Mg and HCl with different concentrations; we talked about how we can measure rate by how long it takes to bubble, measuring pressure with time, etc. I did the heterogeneous/homogeneious catalytic decomposition of H2O2.)

Thursday: Do lab to determine activation energy

Friday: Work day. Handed out practice test.

Week of 10/28


Monday: I took the afternoon off to hang out with my mom. You guys watched the reaction mechanisms video, took notes and did some practice problems in the textbook.

Tuesday: Still hanging out with my mom – you guys were to read an ozone article and answer the questions and then read some of the textbook to review what you’d learned about reaction mechanisms and catalysts.

Wednesday: The first half of the class we reviewed a bunch of reaction mechanism stuff that was unclear from when I was gone.  Then I went over integrated rate laws – how concentration depends on time.  We did a couple of problems with the integrated rate laws and then I showed you how to determine order using graphs.  Homework was to do the pre-lab for the kinetics of dye fading.

Thursday:  We did the kinetics of dye fading lab.  It doesn’t take very long, but the food coloring did not give nice results. So it took awhile to do the graphing. Next year do the flinn version where you add 2 drops to 100 mL water and then add 10 mL bleach. Then take that solution and put in cuvette.  Also handed out unit outline.

Friday: Time to work on lab and homework.
