For a solute undergoing association in a solvent, the van't hoff factor

A

is always greater than one

B

has zero value

C

is always less than one

D

has negative value

Text Solution

Verified by Experts

The correct Answer is:
3
vant's hoff factor, I, is defined as:
`i=("observed colligative property")/("calculated colligative property")`
For a solute undergoing association in a solvent, the van't hoff factor is always less than one because due to association, the total number of moles of particles decreases and hence observed colligative property is less than calculated colligative property
