Phase Diagrams — Thermodynamic Stability & Phase Transitions
Chemistry
PhD-level treatment of one-component and binary phase diagrams: Gibbs phase rule, chemical potential equality, Clausius-Clapeyron equation, Maxwell equal-area construction, van der Waals fluid, eutectic systems, lever rule, and three fully interactive explorers.
Learning Objectives
- Apply the Gibbs phase rule to determine degrees of freedom for any system
- Derive and apply the Clausius-Clapeyron equation for all phase boundaries
- Interpret binary phase diagrams using tie lines and the lever rule
- Understand the van der Waals equation and the Maxwell construction
- Use the interactive tools to predict phase behaviour from thermodynamic parameters
