A full, clearly sequenced unit (72 slides) covering Topic 23 Entropy & Gibbs Free Energy for AS/A Level Chemistry. Entropy, spontaneity, ΔG, feasibility and temperature effects with diagrams, animations and fully worked examples.

This PowerPoint directly addresses the specification points shown on slides 2–3, including:
• Entropy (S) as dispersal of energy and disorder
• Predicting entropy changes from physical and chemical processes
• Standard molar entropy values and comparisons
• Total entropy change (ΔS total)
• Feasibility and spontaneity
• Gibbs Free Energy: ΔG = ΔH – TΔS
• Temperature dependence of spontaneity
• Linking entropy to equilibrium

What This Resource Provides
• Clear explanations of entropy, disorder and probability
• Click-in animations illustrating diffusion, particle distribution and energy dispersal
• Fully worked ΔS, ΔH, T and ΔG calculations
• Graphical interpretation of spontaneity and temperature effects
• Summary tables for predicting feasibility
• Exam-style questions and structured practice
• Fully aligned with Cambridge International 9701 specification

Bundle

Complete CIE A2 Chemistry (9701) High Quality Bundle – Topics 19–30

This A2 Chemistry bundle provides every PowerPoint required to teach Topics 19–30 of the Cambridge International A Level Chemistry (9701) syllabus. All content aligns precisely with the CIE textbook and exam expectations, including advanced physical, inorganic and organic chemistry. Topics Include: 19. Lattice Enthalpy & Born–Haber Cycles 20. Electrochemistry 21. Further Equilibria 22. Reaction Kinetics (A2) 23. Entropy & Gibbs Free Energy 24. Transition Metals 25. Benzene & Electrophilic Substitution 26. Carboxylic Acids & Acyl Derivatives 27. Organic Nitrogen Compounds 28. Polymerisation 29. Organic Synthesis 30. Analytical Chemistry (Chromatography, GLC, NMR, Spectroscopy) Topics 19–22 — Fully Planned, Ready-to-Teach Lesson Units These PowerPoints follow a structured, lesson-based format with consistent pedagogy to support both new and experienced A Level teachers. Each unit is fully sequenced so teachers can deliver challenging A2 content with clarity and confidence. Key Features • Starter slides with lesson number, title and learning goals in a yellow box • Retrieval starters or warm-up questions at the beginning of each lesson segment • Chunked explanations for complex ideas (Born–Haber cycles, electrode potentials, feasibility, kinetics) • Click-in animations for modelling, annotation, and gradual reveal of diagrams, equations and steps • Worked examples embedded throughout, followed by short AfL checks • Independent practice tasks matched to CIE exam phrasing • Plenaries linked to initial learning objectives • End-of-topic assessment questions in full exam style Topics 23–30 — Knowledge-Rich, Example-Driven PowerPoints These later A2 topics are designed as high-quality content presentations packed with clear explanations, fully worked examples, high-level diagrams and exam-focused structure. They are perfect for direct teaching, revision, flipped lessons or teacher subject-knowledge support. Key Features • Exam-aligned definitions in bold, matching Cambridge mark scheme language • Fully worked calculation examples, including ΔG, entropy, Ksp, Kpc, rate laws, redox, and spectroscopic interpretation • Mechanisms and processes explained step-by-step, including transition-metal redox cycles, electrophilic substitution on benzene, nucleophilic acyl substitution, peptide formation and more • High-quality diagrams and animations for energetics, transition-metal complexes, ligand substitution, orbital splitting and polymer formation • Scaffolded walkthroughs for complex A2 calculations (Gibbs free energy, partition coefficients, buffer pH, solubility product, Nernst equation) • Summary tables of conditions, reagents, mechanisms and functional-group transformations • Exam-style questions throughout, ideal for modelling or independent work • Perfect for note-taking, revision and board modelling during fast-paced A2 lessons Why Choose This A2 Bundle? • Covers the entire A2 syllabus (9701) • Consistent structure and formatting across all topics • Ideal for complete course delivery, revision or intervention • Supports early-career teachers with structured pedagogy (Topics 19–22) • Supports high-attaining A2 students with rich content and worked examples (Topics 23–30) • Saves extensive planning time while maintaining teacher autonomy
