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

For solutes which do not undergo any association or dissociation in a solute, van't Hoff factor (i) will be

In case a solute associates in solution, the van't Hoff factor,

One mole of a solute A is dissolved in a given volume of a solvent. The association of the solute take place as follows: nArarrA_(n) If a is the degree of association of A, then van't hoff factor i is expressed as:

One mole of a solute A is dissolved in a given volume of a solvent. The association of the solute take place as follows: nA rarr A_(n) . If a is the degree of association of A , the van't hoff factor i is expressed as:

For solutes which do not undergo any association or dissociation in a solute, Van't Hoff factor (i) will be

Acetic acid undergoes dịmerisation in benzene solution, the van't Hoff factor i is related to the degree of association of the acid as

In association of solute, the Van't Hoff factor is greater than unity.

In association of solute, the Van't Hoff factor is greater than unity.

In association of solute, the Van't Hoff factor is greater than unity.
