Experienced biology, chemistry (gen, AP, orgo, biochem), tutor, who emphasizes understanding and helps prep for MCAT/DAT/OAT exams

The student and tutor worked through problems related to chemical kinetics and redox reactions. They practiced calculating activation energy and the pre-exponential factor using the Arrhenius equation and then delved into the detailed steps of balancing complex redox reactions, including identifying oxidation states, writing half-reactions, and balancing ionic and molecular equations in acidic conditions. They planned to practice similar problems in a future session.

The Student and Tutor worked through problems related to oxidation-reduction reactions, Gibbs Free Energy and spontaneity, and chemical kinetics, including rate laws and the Arrhenius equation. They practiced balancing redox reactions, calculating thermodynamic values, and interpreting kinetic data from graphs. The Tutor plans to find more practice problems on balancing half-reactions for the next session.

The tutor and student worked through a practice exam covering topics in chemistry, including acid-base theory (Bronsted-Lowry), pH calculations, properties of explosives, oxidation states, redox reactions, entropy, thermodynamics (Gibbs Free Energy), kinetics (rate laws), and buffer systems. They practiced identifying conjugate pairs, calculating pH, predicting entropy changes, and understanding spontaneity. The next session is planned to finish the review and cover additional student-submitted questions.

The class reviewed gas laws, including the combined gas law and the Kelvin scale, and practiced solving related problems. The session then explored the Maxwell-Boltzmann distribution of particle speeds and the relationship between kinetic energy, mass, and velocity, using graphs and equations to illustrate these concepts.

The Student and Tutor worked through problems requiring dimensional analysis, including unit conversions for toxicity calculations and rate conversions. They practiced setting up and solving complex multi-step conversions to arrive at desired units, and planned to continue practicing these skills in future sessions.

The student and tutor reviewed concepts related to the kinetic theory of gases, including pressure, temperature, and their relationships with molecular motion. They practiced identifying independent, dependent, and controlled variables in gas experiments and analyzed the behavior of gases in both flexible and non-flexible containers. The session also touched upon expressing these relationships algebraically and understanding molecular-level explanations for gas behavior.
