Lesson 2.1: Thermodynamics and Chemical Equilibrium

This lesson focuses on the principles that govern energy changes in chemical reactions. Students are guided through concepts like enthalpy, entropy, Gibbs free energy, and spontaneity with clear reasoning and real-world connections. Numerical problem-solving techniques are explained in a structured manner to improve accuracy and speed.

Chemical and ionic equilibrium are covered in depth, with emphasis on Le Chatelier’s principle and equilibrium constants. Students learn to analyze reaction conditions and predict system behavior, a key skill required for competitive exams.
