Foundations of Chemical Thermodynamics and Thermochemistry

Understanding how energy flows and why chemical reactions occur is fundamental to mastering physical chemistry. This text-based course guides you through the core principles of thermodynamics and thermochemistry without unnecessary complexity. By the end of this course, you will develop a strong conceptual foundation and the problem-solving skills needed to analyze energy changes, heat transfer, and reaction spontaneity. What you'll learn: Understand the fundamental laws of thermodynamics and their applications to chemical systems; Calculate enthalpy changes, heat capacity, and internal energy using Hess's Law and calorimetry principles; Analyze entropy and Gibbs free energy to predict the spontaneity of chemical reactions; Apply modern IUPAC conventions and standard state definitions to thermodynamic calculations; Practice solving step-by-step numerical problems designed to reinforce core chemical principles. The course starts with essential terminology, system definitions, and state functions before moving into detailed explorations of thermochemical equations and spontaneous processes. You will progress through structured written explanations and practice exercises designed to build your confidence. This course is designed for beginning chemistry students, pre-university science learners, and anyone looking to build a rock-solid foundation in physical chemistry, with no prior advanced chemistry knowledge required.
