Question 43

Multiple Choice

Which statement regarding nonideal solutions is NOT correct?


A) The boiling point of a nonideal solution is always higher than that of an ideal solution.
B) Ideal solutions follow Raoult's law, where the total vapor pressure is the sum of the mole fractions of the volatile components multiplied by their vapor pressure when they are pure (Ptotal =x1P1 + x2P2 +…) .
C) When adhesive forces are stronger than cohesive forces in the solution, negative deviations from Raoult's law are observed.
D) Positive deviations from Raoult's law are observed when solute-solute and solvent-solvent interactions are stronger than solute-solvent attractions.
E) Raoult's law applies to mixtures of volatile components.
