Understand the core concepts of electrochemistry in this comprehensive lecture on Electrode Potentials, Gibbs Free Energy, and the Nernst Equation. This lesson explains how electrochemical cells generate electrical energy, how electrode potentials determine reaction direction, and how Gibbs free energy relates to cell voltage and reaction spontaneity.

You will also learn how the Nernst Equation predicts cell potential under non-standard conditions and how equilibrium constants are connected to electrochemical reactions. The lecture includes clear derivations, solved numerical examples, and practical applications for university chemistry students, competitive exams, and research preparation.
