Chemical Equilibria and Reactivity
This lecture covers advanced topics in general chemistry, focusing on chemical equilibria and reactivity. It discusses the relationship between standard potentials, free enthalpy, and equilibrium constants in redox reactions. The Nernst equation is introduced to predict changes in cell potential with concentration and pressure. Various types of electrochemical cells, such as concentration cells and fuel cells, are explained. The lecture also explores the role of pH in redox reactions and the use of different reference electrodes. Additionally, it delves into the concept of membrane potential in biological systems and the principles of electrolysis.
