3. Heuristics for predicting the non-ideality of a mixture
3.1 Prediction of a deviation from Raoult's law
Predicting deviations from Raoult's law remains approximate, but is possible based on the ability to form interactions between components of different chemical families (donor or acceptor constituents, active or inactive hydrogens) and the bubble temperature difference between pure components.
