Liquid mixtures can exist in a single phase. However, they may also separate into multiple liquid phases. This episode covers liquid-liquid phase equilibrium under constant temperature and pressure. First, we determine the conditions for liquid-liquid phase equilibrium using fugacity. We then examine the Gibbs free energy behavior in phase equilibrium,.
In this episode, we cover the equilibrium between solids and liquids. Like before, we discuss the equilibrium using fugacity and predict the composition of the mixture based on thermodynamic properties. Finally, we compare predicted values with experimental data using naphthalene as an example.
When dealing with the equilibrium of a specific system, we often utilize fugacity. In this episode, we discuss methods for estimating the fugacity of components and explore the vapor-liquid equilibrium in mixtures using the methods.
Equilibrium is a crucial thermodynamic concept, representing a state where there is no change over time when observed on a macroscopic scale. In this episode, we cover the equilibrium criteria based on different systems. Finally, we discuss the properties of a closed system (given temperature and pressure) at phase equilibrium.
There are differences between the actual properties and the ones in the ideal state. In this episode, we discuss the concepts of residual properties and excess properties that refer to the differences. Finally, we cover a new property called fugacity by comparing the property in the real state with the ideal state.
Thermodynamics allows us to analyze and predict various phenomena. In this episode, we describe the fundamental information required for understanding thermodynamics. Firstly, we discuss the definition and types of systems and the laws of thermodynamics. Finally, we summarize the relationships among thermodynamic properties.
