Question
Since they have near-zero enthalpy of mixing, heptane and hexane are a commonly cited example that this law applies to. For 10 points each:
[10m] Name this higher concentration analogue of Henry's law. Positive and negative azeotropes deviate from this law in opposing directions.
ANSWER: Raoult's law
[10e] Zero enthalpy of mixing characterizes the ideal type of these systems, which Raoult's law applies to. The concentration of these mixtures can be given as molarity or molality.
ANSWER: solutions
[10h] The effect of interactions on enthalpy of mixing is reflected by the parameter chi ("kye") in this theory of polymer solutions. Chi appears in an equation for Gibbs free energy in this doubly eponymous theory.
ANSWER: Flory–Huggins solution theory
