The walkthrough shows the exam‑marking points in purple, and the thinking‑out‑loud development and annotations in red/purple, so you can clearly see what earns marks and what helps you understand the chemistry. It covers key ideas that appear across A‑Level Chemistry, including equilibrium moles and concentration, constructing the Kc expression, calculating Kc and its units, and applying Le Chatelier’s Principle to predict changes in equilibrium position. ⭐ What this walkthrough covers Using moles and concentration to set up equilibrium tables Constructing the Kc expression correctly Calculating Kc and determining its units Applying Le Chatelier’s Principle to explain shifts in equilibrium ⭐ Chapters 00:00 Intro & Socials 00:05 How to use this walkthrough 00:49 Equilibrium Moles and Concentration 03:16 Kc Expression, calculation and units 07:09 Le Chatelier’s Principle ⭐ How this was made This walkthrough was created using slide‑based explanations, with colour‑coded annotations to separate exam‑marking points from the thinking process, so you can pause, rewatch and build your own written answers from the structure shown. 📲 Connect with Us: 📸 Instagram: @chemistrytutor123 🎵 TikTok: @chemistrytutor123 📧 Email: [email protected]
