Equilibrium Day 2

Greetings,

From today you should be able to
(1) given an llbm equation, write an llbm expression
              (K=[products]/[reactants])
(2) Given an llbm equn and its K value, determine the value of K for a manipulated equn (see manipulating K handout on moodle - if it is not there yet, it will be there soon)
(3) Write an llbm expression given an llbm equn that includes solids - don't include pure solids in the llbm expression
(4) Solve for K given an llbm equation and llbm concentrations

From today: Hmwrk:
p442 (1)   p444(2,3,4)   p445(5, 6)   p447(7bc) -read the example above the questions! and finally -  p449(3,4,6) -info given about llbm equn, write K epxression, solve for unknown

Additional question: How does the size of the K value convey information about the [product] and [reactant]?    [product] ...i.e. concentration of product

For next day - prepare for llbm lab (handout available on moodle under the equilibrium section - (Qualitative llbm lab)
preparing for the lab? -read it over, set up your lab book, consult the textbook, think about how the results are going to be used? [What concept is this lab trying to cover?]

One more moodle tidbit - the llbm unit outline is on there as well

That is it for me today. Closing thought? Sometimes you are the bug, sometimes you are the windshield. Okay...that's all I have for now.
