This bundle provides companion notes and editable PowerPoint files for IB DP Chemistry Topics R1.1 to R3.4, aligned with the IB Chemistry 2026 syllabus. The materials are designed to help teachers organise lesson content and provide students with structured notes for revision.

In the IB Chemistry course, topics are organised around two main ideas: structure and reactivity. Structure explains the nature of matter, while reactivity focuses on how and why chemical reactions occur.

This bundle covers the Reactivity section of the syllabus, which explores the factors that drive chemical reactions, how fast they occur, how far they proceed, and the mechanisms behind them.

Topics Included

Reactivity 1 – What Drives Chemical Reactions?

R1.1 Enthalpy Change

R1.2 Energy Cycles

R1.3 Energy from Fuels

R1.4 Entropy & Spontaneity

Reactivity 2 – How Much, How Fast and How Far?

R2.1 How Much? (Stoichiometry)

R2.2 How Fast? (Reaction Rates)

R2.3 Extent of Chemical Change (Equilibrium)

Reactivity 3 – Mechanisms of Chemical Change

R3.1 Proton Transfer Reactions (Acid–Base Chemistry)

R3.2 Electron Transfer Reactions (Redox Chemistry)

R3.3 Electron Sharing Reactions (Free Radical Reactions)

R3.4 Electron-Pair Sharing Reactions (Organic Reaction Mechanisms)

These topics explore key concepts such as thermodynamics, reaction rates, equilibrium, acid–base chemistry, redox reactions, and organic reaction mechanisms, which together explain how chemical reactions occur and why they proceed under certain conditions.

What’s Included

Companion notes for each topic (PDF format)

Editable PowerPoint versions of the notes

Content organised according to the IB Chemistry 2026 syllabus

Structured explanations designed for lesson planning and revision

The materials can be used as teacher reference notes, student study notes, or revision summaries.

Important Note About the PowerPoint Files

The PowerPoint files are not classroom-ready presentations.

They are simply editable versions of the companion notes provided in slide format. The slides contain the same information as the PDFs and are intended for teachers to adapt, modify, or reorganise when preparing their own classroom presentations.

Typical Uses

Teachers commonly use this bundle to:

organise lessons for IB Chemistry reactivity topics

provide structured topic notes for students

adapt slides into their own presentations

support revision and exam preparation

This bundle provides a complete set of structured teaching notes and editable materials for IB Chemistry Topics R1.1–R3.4, covering the major reactivity concepts in the IB Chemistry course.
