Gibbs Free Energy and Equilibrium Constant Explained | Thermodynamics Class 11 | ChembyKKSir

⸻

🌍 Namaste Dear Students! 🙏

Welcome to Lecture 9 Part 3 of Thermodynamics and Thermochemistry — the final and most important part of the Entropy and Gibbs Free Energy series.

In this lecture, I, Krishna Kumar Sah (ChembyKKSir), have completed the full concept of Gibbs Free Energy (Delta G), Entropy Change (Delta S), and the mathematical and conceptual connection between spontaneity, temperature effect, and equilibrium constant (K).

You will clearly understand the conditions for spontaneity, the relation Delta G = Delta H – T Delta S, and how changes in enthalpy and entropy decide whether a reaction is spontaneous or not. Detailed discussion on the effect of temperature when Delta H and Delta S have different signs has also been given with logic and examples.

⸻

💡 In Lecture 9 Part 3 You Will Learn
• Derivation and meaning of Delta G = Delta H – T Delta S
• Complete conditions for spontaneity of reaction
• Total entropy of universe greater than zero (Delta Suniv 0)
• Delta G less than zero condition for spontaneous reactions
• Effect of temperature on spontaneity when Delta H and Delta S are positive or negative
• Four temperature cases explained logically
• Relation between Gibbs Free Energy and Equilibrium Constant (K)
• Derivation of Delta G = –RT ln K
• Importance of Gibbs Energy in predicting equilibrium and spontaneity
• Conceptual and numerical understanding for JEE, NEET and CBSE
