Thermodynamics of Mixing Let’s think of the lattice model in the book – simulates a liquid of two different things There are N total sites each filled with either an A or a B molecule (sketch lattice) N = NA + NB Let’s think about the entropy of the situation What are the number of arrangements? W = N! / NA!NB! What about A and B |

The average intrinsic properties of a mixture can be classi?ed using either a molar base or a mass base For instance the internal energy per unit mass of a mixture u is determined by summing the internal energy per unit mass for each species weighted by the mass fraction of the species u ¼ U m ¼ P i m iu i m ¼ X i y iu |

What is the difference between Gibbs energy and thermodynamic potential?
- is the Helmholtz energy, g is the Gibbs energy, v is the volume, T e temperature,is th and p is the pressure. Thermodynamic potentials are equivalent because they are Legendre-transforms of each other. The two potentials with measurable quantities as independent variables are the Gibbs energy g and the Helmholtz energy a
Are there other mixing rules for the mixture covolume B M?
