Question
Select correct statement :
Options
A.Solution has more molecular randomness than a pure solvent has, the entropy change between solution and solid is larger than the entropy change between pure solvent and solid
B.Heats of fusion of solution and solvent are similar since similar forces of intermolecular forces are involved
C.Sugar containing solution freezes at a lower temperature than pure water
D.All are correct statements
Solution
(A) Entropy of solution > Entropy of pure solvent
(ᐃS)solution-solid > (ᐃS)solvent-solid
In solution, number of particle is greater so solution have greater entropy.
(B) Only solvent involved in solid-liquid equilibrium.
(C) ᐃTf = Tsolvent - Tsolution
