Fundamentals of Electrochemistry: Cells, Potentials, and Energy

Electrochemistry governs essential processes from generating power in batteries to preventing metal corrosion. Understanding these principles is critical for anyone studying physical science or engineering. By the end of this course, you will have a robust understanding of how chemical energy is converted into electrical energy and vice versa. You will be able to analyze electrochemical systems, calculate key thermodynamic variables, and apply these concepts to practical scenarios like conductivity and cell design. What you'll learn: * Understand the definitions and components of galvanic and electrolytic cells and proper cell notation. * Calculate standard cell potential (E°) and electromotive force (EMF) using standard reduction potential data. * Apply the Nernst equation to determine cell potential under non-standard conditions and concentration cells. * Analyze the relationship between cell potential, Gibbs free energy (ΔG), and the equilibrium constant (K) to predict reaction spontaneity. * Master the concepts of molar conductivity, resistivity, and their application to strong and weak electrolytes (Kohlrausch's Law). * Practice applying Faraday's laws of electrolysis to quantitative problems involving mass and charge transfer. The course begins with foundational definitions of redox reactions and cell components, progressing systematically through thermodynamics and kinetics. We conclude by examining the quantitative methods for conductivity and the principles of electrolysis. This course is designed for absolute beginners in physical chemistry. No prior advanced knowledge of thermodynamics or electricity is required, only a basic familiarity with general chemistry concepts.
