Molecular Models and Equations of State
One of the key aspects of molecular thermodynamics of phase equilibria is the use of molecular models and equations of state to describe the properties and interactions of molecules in different phases. Molecular models are simplified representations of molecules that capture their essential features, such as size, shape, polarity, and charge. Equations of state are mathematical expressions that relate the pressure, volume, temperature, and composition of a fluid or a mixture.
Molecular models and equations of state can be classified into different types according to their level of complexity and accuracy. For example, some common types are:
Ideal gas model and equation of state: This is the simplest model and equation of state that assumes that molecules have no volume and no interactions. It is only valid for very low pressures and high temperatures.
Van der Waals model and equation of state: This is a more realistic model and equation of state that accounts for the finite size and attractive forces between molecules. It is valid for moderate pressures and temperatures.
Cubic equations of state: These are equations of state that have a cubic form in terms of the compressibility factor. They are more accurate than the van der Waals equation of state and can be modified to include different molecular models. Some examples are the Redlich-Kwong equation of state, the Soave-Redlich-Kwong equation of state, and the Peng-Robinson equation of state.
Statistical mechanics models and equations of state: These are models and equations of state that are derived from the principles of statistical mechanics, which is the branch of physics that deals with the behavior of large numbers of particles. They are more rigorous and general than the previous models and equations of state, but they are also more complicated and difficult to solve. Some examples are the Lennard-Jones model, the hard-sphere model, and the virial equation of state.
Molecular Thermodynamics of Phase Equilibria by Prausnitz and his co-authors covers all these types of molecular models and equations of state in detail. It also explains how to use them to calculate thermodynamic properties such as fugacity, activity, chemical potential, enthalpy, entropy, Gibbs free energy, etc. Extra Speed Solucionario provides solutions for all the problems related to these topics in the book.
Phase Equilibria Criteria and Calculations
Another important aspect of molecular thermodynamics of phase equilibria is the use of phase equilibria criteria and calculations to determine the conditions under which different phases coexist in equilibrium. Phase equilibria criteria are based on the concepts of equilibrium thermodynamics, which states that at equilibrium, the total Gibbs free energy of a system is minimized. Phase equilibria calculations are methods to find the equilibrium compositions, pressures, temperatures, etc. for different phases.
Phase equilibria criteria and calculations can be applied to various types of phase equilibria problems, such as:
Vapor-liquid equilibrium (VLE): This is the type of phase equilibrium that occurs when a liquid mixture is in contact with its vapor phase. The VLE criteria states that at equilibrium, the chemical potential or fugacity of each component in both phases must be equal. The VLE calculations can be done using various methods, such as graphical methods (e.g., T-x-y diagrams), analytical methods (e.g., Raoult's law), or numerical methods (e.g., Newton-Raphson method).
Liquid-liquid equilibrium (LLE): This is the type of phase equilibrium that occurs when two immiscible or partially miscible liquid phases coexist in a mixture. The LLE criteria states that at equilibrium, the chemical potential or activity of each component in both phases must be equal. The LLE calculations can be done using various methods, such as graphical methods (e.g., triangular diagrams), analytical methods (e.g., NRTL model), or numerical methods (e.g., UNIFAC method).
Solid-liquid equilibrium (SLE): This is the type of phase equilibrium that occurs when a solid phase (e.g., a crystal or a polymer) coexists with a liquid phase in a mixture. The SLE criteria states that at equilibrium 04f6b60f66
