In this video, we dive deep into the concept of Spontaneity in Thermochemistry for Class 11 Chemistry. We explore why certain chemical reactions occur on their own while others require external energy. Understanding the true drivers of chemical reactions: Entropy and Gibbs Free Energy.

What you will learn:

Definition of Spontaneous and Non-spontaneous processes.
The role of Entropy (S) in determining spontaneity.
Introduction to Gibbs Free Energy (G) and the Gibbs-Helmholtz equation.
Criteria for spontaneity...etc..
This lesson is essential for CBSE, ICSE, and competitive exams like JEE and NEET.
