The van't Hoff factor of solutes A, B an...

The van't Hoff factor of solutes A, B and C in aqueous solutions are 0.8, 1.6 and 1.2, respectively. The freezing point of equimolar solutions follow the order

A

`A gt B gt C`

B

`A gt C gt B`

C

`B gt A gt C`

D

`B gt C gt A`

Text Solution

Verified by Experts

The correct Answer is:
B
`Delta T_(f)= ik_(f)m` for equimolar solutions, larger the van.t Hoff factor, larger the decrease in freezing point and hence minimum will be the freezing point.
