The student and tutor worked through calculating pH for weak acid-weak base titrations. They practiced setting up ICE tables, using Ka and Kb values, and applying the quadratic formula to solve for concentrations at various points in the titration, including before the equivalence point, at the equivalence point, and after passing the equivalence point.

The tutor and student reviewed concepts related to chemical equilibrium, focusing on Le Chatelier's Principle and the reaction quotient (Q) versus the equilibrium constant (Keq). They also covered the definitions and differences between Arrhenius, Brønsted-Lowry, and Lewis acids and bases, with a particular focus on identifying conjugate acid-base pairs.

The Student and Tutor reviewed concepts of chemical equilibrium, including phase equilibrium, equilibrium constants (Keq, Ksp, Kc), and Le Chatelier's principle. They practiced identifying factors that affect equilibrium and how systems shift to re-establish it, with a plan to continue discussing theoretical concepts in the next session.

The tutor and student worked through problems related to chemical kinetics and thermodynamics. They reviewed rate laws, reaction orders, and methods for determining them from experimental data, including graphical analysis. They also practiced applying Hess's Law to calculate enthalpy changes by manipulating and summing given chemical reactions and their enthalpies.

The Tutor and Student worked through a complex problem involving chemical kinetics, specifically focusing on determining reaction orders, rate laws, and rate constants using experimental data. They practiced calculating individual reactant orders and the overall reaction order, then used this information to find the rate constant and predict reaction rates.

The Student and Tutor focused on understanding and applying Hess's Law in chemistry, working through multiple practice problems to master the technique. They practiced rearranging chemical equations, adjusting enthalpy values, and summing them to determine the overall enthalpy change for a reaction. The Tutor provided practice problems for the Student to work on independently before their next session.
