IB Chemistry S2.2 the Covalent Model Lessons

This lesson delivers structured, step-by-step lessons that guide students through every part of the IB Chemistry syllabus for S2.2 The covalent model. These lessons simplify complex ideas like chemical kinetics, thermodynamics, and equilibrium systems, while worked examples show how to approach IB-style questions.

Designed for both HL and SL learners, RevisionDojo lessons ensure students not only understand the theory but also know how to apply it in IB Paper exam situations.

With clear explanations, active learning checks, and a syllabus-first design, RevisionDojo makes revision less overwhelming and more effective.
