Thermochemistry: Principles of Heat and Energy in Reactions

Thermochemistry is the essential branch of physical chemistry that connects energy and matter. Understanding how heat is transferred and transformed during reactions is crucial for analyzing any chemical system. This course provides a rigorous, text-based foundation in thermochemistry and thermodynamics. You will move beyond simple definitions to grasp the fundamental laws governing energy, allowing you to confidently solve problems involving enthalpy, Hess's Law, calorimetry, and reaction spontaneity. What you'll learn: * Understand the First Law of Thermodynamics and the relationship between internal energy, heat, and work. * Apply Hess's Law and standard enthalpies of formation to calculate reaction heats accurately. * Practice solving problems related to calorimetry and heat capacity determination. * Master the concepts of entropy and the Second Law, predicting the direction of spontaneous change. * Calculate Gibbs Free Energy changes and relate them to reaction feasibility and equilibrium constants. The course begins with foundational definitions and the laws of thermodynamics before progressing to practical applications like calculating enthalpy and using calorimetry data. The final sections focus on mastering entropy and Gibbs Free Energy to predict the spontaneity of chemical processes. This foundational course is designed for absolute beginners in physical chemistry, including students preparing for rigorous science programs.
