This bundle of PowerPoints covers IBDP Chemistry SL R2: How Much, How Fast and How Far? for first examination 2025, bringing together quantitative chemistry, kinetics and equilibrium in one structured teaching resource. It is designed to help students build secure understanding across the whole SL R2 topic, from writing equations and calculating yields to explaining reaction rates and predicting equilibrium changes.

In IBDP Chemistry, this area of the course focuses on three linked ideas: how much chemical change occurs, how fast it happens, and how far a reversible reaction proceeds before reaching equilibrium. This bundle supports students in mastering those ideas step by step. The lessons move from stoichiometry and reacting ratios, through collision theory and Maxwell–Boltzmann distributions, to physical and chemical equilibrium, Kc and Le Châtelier’s principle. This makes the bundle ideal for teaching the full SL R2 topic in a coherent sequence rather than as isolated lessons.

The bundle includes 11 editable PowerPoint (.pptx) lessons:
R2.1 Chemical Equations, Reacting Ratios, Limiting and Excess Reactants, Theoretical and Percentage Yield, and Atom Economy.
R2.2 Rate of Reaction, Factors Affecting the Rate of Reaction, and Maxwell–Boltzmann Distribution Curves.
R2.3 Physical Equilibrium, Chemical Equilibrium, The Equilibrium Constant Kc and Magnitude of Kc, and Le Châtelier’s Principle.

Across the bundle, students are supported with retrieval starters, key word definitions, worked examples, calculations, graph interpretation, particle-level explanations, and practice questions with answers. The resources are suitable for first teaching, revision, cover lessons or flipped learning, and they align closely with the IBDP Chemistry specification for first examination 2025.

File types included: editable PowerPoint (.pptx) files.

Last updated: 2026 – refined lesson sequencing, improved clarity of calculations and explanations, and enhanced practice tasks across stoichiometry, kinetics and equilibrium.
