Solution Thermodynamics and Maxwell Relations for Chemical Engineers

Thermodynamics forms the backbone of chemical engineering and physical chemistry, yet deriving complex equations and applying them to real mixtures can feel overwhelming. This text-based course breaks down the mathematical frameworks of solution thermodynamics into clear, logical steps. You will transition from basic thermodynamic definitions to confidently analyzing phase behavior and multi-component mixtures. By reading through structured explanations and working through practical problems, you will develop a deep intuitive grasp of how energy and matter interact in chemical systems. You will learn to derive key equations from scratch and apply them to standard industry scenarios and competitive exam-style questions. What you'll learn: - Derive and apply Maxwell relations to calculate unmeasurable thermodynamic properties from experimental data - Analyze phase transitions using the Clapeyron and Clausius-Clapeyron equations - Calculate partial molar properties to describe the behavior of individual components in a mixture - Formulate and solve the Gibbs-Duhem equation to verify the consistency of experimental phase equilibria data - Understand real solution behavior using activity coefficients, fugacity, and excess properties - Practice solving complex thermodynamic problems step-by-step using written exam-style prompts This course begins with foundational concepts, establishing a clear understanding of state functions and thermodynamic potentials before introducing multi-component systems. You will progress systematically through pure species behavior, ideal solutions, and finally, non-ideal mixtures. This course is designed for undergraduate chemical engineering students, chemistry majors, and anyone preparing for technical competitive exams who wants to master thermodynamics from the ground up without complex prerequisites.
