In this session, we take a deep dive into Entropy Calculations, an essential part of the Chemical Energetics topic. Learn how to calculate entropy change (ΔS) and understand its importance in predicting the feasibility of reactions. What You’ll Learn in This Class: 1️⃣ Understanding Entropy (ΔS) What entropy means in physical and chemical systems Factors affecting entropy: state changes, number of particles, complexity How entropy relates to order and disorder 2️⃣ Calculating Entropy Change Using standard entropy values to calculate ΔS for a reaction Applying the formula: ΔS = ΣS(products) − ΣS(reactants) Interpreting positive and negative entropy changes 3️⃣ Linking ΔS to Feasibility Introduction to Gibbs free energy: ΔG = ΔH − TΔS When reactions are spontaneous (feasible) based on ΔG The role of temperature in determining spontaneity 4️⃣ Past Paper Questions Solved Step-by-step walkthrough of structured entropy questions Calculation methods, units, and scientific reasoning Common mistakes and how to avoid them in exam responses Why Join Mega Lecture?
