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

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.

The Tutor and Student reviewed enzyme kinetics, focusing on calculating rate constants (K2, KM, K1, K-1) using experimental data and theoretical equations. They then transitioned to discussing Beer-Lambert Law, including practical aspects like unit analysis and plotting absorbance versus path length. The next session will involve further practice with unit conversions and potentially finishing a problem set.

The tutor and student reviewed concepts related to acid-base titrations, including titration curves, equivalence points, and pKa determination using half-equivalence points. They also practiced writing balanced neutralization reactions and began exploring chemical kinetics, specifically zero and first-order reactions, and how to determine rate constants (k2) and Michaelis constants (Km) from experimental data.

The tutor and student reviewed Gibbs free energy, spontaneity, and chain reactions involving free radicals. They practiced calculating enthalpy changes for explosions and determining the enthalpy per gram for explosives like RDX and TNT. The session concluded with exercises on unit conversion for enthalpy calculations.
