1
Q
negative deviation from raoult’s law
A
ΔH<0: solute/solvent interaction are stronger than solute/solute interactions or solvent/solvent interactions (exothermic)
2
Q
positive deviation from raoult’s law
A
ΔH>0: solute/solvent interaction are weaker than
solute/solute interactions or solvent/solvent interactions (endothermic)
3
Q

A
Having a low vapor pressure at ordinary temperatures (does not evaporate easily)
4
Q

A
Having a high vapor pressure at ordinary temperatures (evaporates easily)
5
