Foundational Thermochemistry: Energy, Enthalpy, and Entropy

Understanding how energy transforms during chemical reactions is essential for predicting outcomes and optimizing chemical processes. This course provides a rigorous, text-based foundation in the science of thermochemistry. By the end of this program, you will possess a strong conceptual understanding of the First and Second Laws of Thermodynamics and the ability to apply key calculations, including Hess's Law and Gibbs free energy equations, to determine reaction spontaneity and heat transfer. What you'll learn: * Understand the definitions of system, surroundings, state functions, and internal energy (U). * Master the calculation of enthalpy changes using calorimetry, standard formation values, and bond dissociation energies. * Apply Hess's Law and Kirchhoff's equations to solve complex, multi-step thermochemical problems. * Learn the concepts of entropy and Gibbs free energy to accurately predict the spontaneity and equilibrium state of reactions. * Practice solving numerical problems related to heat capacity, work done, and phase transitions. The course begins with core terminology and the laws governing energy transfer, systematically progressing through enthalpy, entropy, and free energy. You will work through detailed examples and practice exercises designed to solidify your problem-solving abilities. This course is designed for absolute beginners in chemistry or physics who need a robust foundation in thermodynamics, requiring no prior knowledge of advanced physical chemistry.
