Welcome to Mega Lecture’s A Level Chemistry Live Class 03! 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
