Chemical and Biological Thermodynamics for Beginners

Thermodynamics is the essential framework for understanding why chemical reactions occur and how biological systems manage energy. Without a solid grasp of energy flow and equilibrium, it is impossible to predict the behavior of molecules or design efficient processes. This course provides a clear, conceptual introduction to the core principles, enabling you to confidently approach problems in chemistry, biochemistry, and materials science. You will gain the skills to quantify energy changes, predict reaction spontaneity, and understand how conditions like temperature and pressure affect equilibrium in both simple and complex systems. What you'll learn: * Understand the First, Second, and Third Laws of Thermodynamics and their implications for energy conservation and entropy. * Calculate key thermodynamic properties, including enthalpy, entropy, Gibbs free energy, and heat capacity. * Apply chemical potential and equilibrium constants (Keq) to predict the extent and direction of chemical and phase transformations. * Analyze the thermodynamics governing the stability and folding of biological macromolecules like proteins and nucleic acids. * Practice solving quantitative problems related to ideal gases, reaction spontaneity, and coupled biological reactions. * Master the concepts of open, closed, and isolated systems and apply them to real-world chemical and biological contexts. The course begins with defining fundamental terminology and systems before moving through the three laws, focusing heavily on Gibbs free energy and equilibrium applications. The final sections integrate these principles by exploring their direct relevance to biological systems. This course is designed for absolute beginners and requires no prior knowledge of advanced chemistry or physics.
