Fri-Day 1
Just finishing playing (and missing every shot) at the charity basketball game in the gym tonight. Will update the blog and post all files by Saturday afternoon.
Have a good weekend (and study too!).
AP Chem- we reviewed kinetic mechanisms in which the rate law predicted from each elementary step does not match the experimental rate law, per se. However, in a case in which an EARLIER (almost always the FIRST step) is FAST and reaches EQUILIBRIUM before the rate determining SLOW step is significantly underway, a SUBSTITUTION can be made into the slow step's rate law after which the rate law predicted MAY agree with the experimental rate law. The first thing that you should check, though, in a mechanism is whether the SUM of the elementary steps adds up to the BALANCED equation.
We then discussed and derived the equations and sketched the various graphs of data for a
ZEROTH order rate law (usually photon-catalyzed decompositions!) and 1ST order rate laws (in which ONE molecule/atom/ion of a given substance is involved in the rate determining step.
We also made a KEY table showing the units of a rate constant, "k", for each of the zeroth, first, second, etc. overall rate law types.
I will post practice problems on Blackboard. Check out the tutorials also.
Bio 6/7- we discussed the structure and function of each part of the excretory system (and diseases thereof) and then we showed any given two systems in your body are working together to overall maintain homeostasis.
Check the review worksheets, quizzes, and objectives answers as part of your study for MONDAY's exam.
Bio 8- we looked at four major respiratory system diseases and then we discussed the structure and function of each part of the excretory system and then we showed any given two systems in your body are working together to overall maintain homeostasis.
Be sure to read in your notes about gout and kidney stones as excretory system diseases.
Check the review worksheets, quizzes, and objectives answers as part of your study for MONDAY's exam.
