A-Level Chemistry Lessons - February, 2026

We’ll explore Group 7 trends, including colours at room temperature and in different solvents, linking these to structure and bond enthalpy. The focus will be on displacement and disproportionation reactions, testing for halide ions, and applying these concepts to challenging exam-style questions.

We’ll cover qualitative analysis techniques for identifying carbonates, sulfates, halides, and ammonia. The focus will be on recognising key tests, observations, and equations, and applying them accurately to exam-style and unfamiliar questions.

We’ll explore enthalpy changes and how to calculate them using bond enthalpies and calorimetry (q=mcΔT)(q = mc\Delta T)(q=mcΔT). The focus will be on interpreting energy profile diagrams, applying Hess’s law, and handling energy loss to tackle challenging exam-style questions with confidence.

We’ll look into the factors affecting reaction rates, linking collision theory to the Boltzmann distribution. The focus will be on how homogeneous and heterogeneous catalysts work, applying Le Chatelier’s principle, and using these ideas to explain and predict outcomes in exam-style questions.
