"We covered chemical kinetics and equilibrium. We began by discussing a generalized reaction profile diagram, and showing how the free energy determines the direction of the reaction, and the activation energy determines its rate of progress. We discussed how chemical kinetics is tested on the MCAT, constructing a rate law from a table of experimental results. We then spent some time correcting or improving the student's understandings of several thermodynamic quantities: work, heat, free energy, enthalpy, bond energies, kinetic energy, potential energy, and entropy. We discussed how free energy, enthalpy, and entropy are all related, and how to predict the sign of Delta-G when Delta-H and Delta-S are oppositely signed. We discussed how to construct an equilibrium expression as well as what information it gave us. We compared that to the reaction quotient, Q. We looped back to a discussion of the change in Gibbs' free energy (Delta G), and how that related to the ratio between Q and K-eq. At this point, time was running out, so I closed with a discussion of STP and standard conditions, and what it meant to discuss the standard versions of thermodynamic state variables (G, H, S)."
"Tonight we finished covering applied arithmetic, specifically probability, averages, rates and work. The student did really well and will continue to practice on her own."
"Worked on a variety of straight math questions and then switched to critical reasoning. Though many of the math problems are ones that you can guess with possible numbers, hopefully we can work out algebraic equations more easily in the future. With the reasoning section, the student is showing impressive logic!"
