Overview
Free energy composition diagrams are essential tools in thermodynamics that illustrate the stability of different phases of a system based on composition and temperature. By analyzing these diagrams, students can gain insights into phase transitions, chemical reactions, and material properties, whic...
Key Terms
Example: G = H - TS, where H is enthalpy, T is temperature, and S is entropy.
Example: Melting ice into water is a phase transition.
Example: In a mixture, the chemical potential helps determine the direction of phase changes.
Example: A stable phase in a free energy diagram is represented by a local minimum.
Example: In a saturated solution, the rate of dissolution equals the rate of crystallization.
Example: The enthalpy change during a reaction can indicate whether it is exothermic or endothermic.
