Chemical Equilibrium and Electrochemistry Fundamentals

Chemical equilibrium and electrochemistry are two critical pillars of physical chemistry, governing how reactions proceed and how energy is converted through electron movement. By mastering the concepts in this course, you will gain a deep understanding of reaction spontaneity, acid-base behavior, solubility, and the operation of electrochemical cells, preparing you for further academic or professional work. What you'll learn: * Understand the criteria for chemical equilibrium, including the equilibrium constant and reaction quotient. * Apply Le Chatelier's principle to predict how changes in concentration, pressure, or temperature affect reaction direction. * Master acid-base concepts (Arrhenius, Brønsted-Lowry, Lewis) and calculate pH using buffer solutions and titration curves. * Learn the principles of oxidation and reduction, standard electrode potentials, and the Nernst equation. * Configure and analyze basic galvanic and electrolytic cells, including modern applications like energy storage systems. * Practice solving complex problems involving solubility product (Ksp) and calculating cell potential under non-standard conditions. This course begins with the thermodynamics of reversible reactions and transitions into detailed coverage of ionic equilibrium in solutions. We then explore the fundamental laws of electrochemistry, focusing on potential, current, and energy conversion processes. This course is explicitly designed for beginners with no prior specialized chemistry knowledge, providing a comprehensive foundation from basic definitions to practical calculations.
