- 9.2: The Gibbs-Duhem Equation
- The Gibbs-Duhem equation relates how the chemical potential can change for a given composition while the system maintains equilibrium. So for a binary system, consisting of components A and B (the two most often studied compounds in all of chemistry)
- 9.4: Ideal Solutions obey Raoult's Law
- Liquids tend to be volatile, and as such will enter the vapor phase when the temperature is increased to a high enough value (provided they do not decompose first!) A volatile liquid is one that has an appreciable vapor pressure at the specified temperature. An ideal mixture continuing at least one volatile liquid can be described using Raoult’s Law.
- 9.5: Most Solutions are Not Ideal
- The Gibbs-Duhem equation relates how the chemical potential can change for a given composition while the system maintains equilibrium. So for a binary system, consisting of components A and B (the two most often studied compounds in all of chemistry)
- 9.7: Activities of Nonideal Solutions
- As seen before activities are a way to account for deviation from ideal behavior while still keeping the formulism for the ideal case intact.
