Lecture 3 Notes: Phase Equilibria
Goal: Understand the general phenomenology of phase
transitionsand phase coexistence conditions for a single component
system.
The Chemical Potential controls phase t
Lecture 5 Notes: Two-Component Phases
How do we use liquid-gas binary mixture phase diagrams?
We use them to find the compositions of the gas and liquid phases at
coexistence.
Consider again our typic

Ideal Gases
Question: What is the composition of a reacting mixture of ideal
gases?
N2(g, T, p) + 3/2 H2(g, T, p) = NH3(g, T, p)
e.g.
What are pN2,pH2, andpNH3
