Question
Freezing point lowering expression is
ᐃTf = Kfm (molality)
Which of the following assumptions are considered for the validity of above equation ?
ᐃTf = Kfm (molality)
Which of the following assumptions are considered for the validity of above equation ?
Options
A.The solution is dilute
B.The ᐃHf (latent heat of fusion of solvent) is independent of temperature between the actual and normal freezing point
C.The solid-phase consists of pure solvent when solution is allowed to cool
D.ᐃTf is not equal to 3Kf for 3 mol L-1 solution
Solution
Since intermolecular forces between solvent molecules are involved, so ᐃH of solution and solvent is almost identical.
