Tues-Day 2
AP Chem- discussed the connection between rate constants and equilibrium constants. Overall, the ratio of the forward rate constant to the reverse rate constant is equal to K, the equilibrium constant. That makes sense in that a large forward rate constant should favor product formation and a large reverse rate constant should favor reactant formation.
We tried another initial condition question in which we compared the reaction quotient, Q, to the given equilibrium constant, K, in order to predict the NET direction of the reaction as it proceeds towards equilibrium.
We then solved a couple of ICE Table equilibrium problems given initial concentrations (or partial pressures) of reactants and products. Final answers to these problems will be posted in the notes on Blackboard.
The MOST IMPORTANT part of these organizing tables is the C (CHANGE) row. The change in concentration (or pressure)of each reactant and product MUST OBEY THE STOICHIOMETRY OF THE BALANCED EQUATION. Do NOT just put +x and -x in that row! Make sure that you USE the coefficient (ratios) from the balanced equation.
Here are tutorials on solving polynomials equations for x in Ti-83 and Ti-89 calculators!
Bio 6- HW OBJECTIVES are due tomorrow, though you can leave out objectives 21 and 22.
We reviewed blood types and did a few problems in which we determined whether or not there would be blood coagulation due to the binding of receiver antibodies to donor red blood cell antigens.
We reviewed the "sensitization" of an Rh- mother who has an Rh+ baby, after which, she has anti-Rh antibodies in her blood plasma. A SECOND Rh+ baby would experience an immune attack from the mother's anti-Rh antibodies.
We then discussed the LYMPHATIC system and its functions of fighting infection via white blood cells (lymphocytes), lymph NODES filtering, and returning plasma back to the blood via the thoracic duct.
We finished with a review of the two specific pathogen fighting immune responses and then we started to discuss the GENERAL immune response against all pathogens or environmental toxins.
Bio 7/8 - HW OBJECTIVES are due tomorrow, though you can leave out objectives 21 and 22.
