When the value of van't Hoff factor is less. than one, this shows that the solute undergoes _______ in the solution.

Explanation

If value of van.t Hoff factor is less than one, this shows that the solute undergoes association in the solution. Since
`i="Number of solute particles after association/dissociation in the solution"/"Number of solute particles originally taken in the solution"`
Thus, if i = 1, (No association/dissociation)
if `ilt1` (Show dissociation)
