If in solvent, n simple molecules of solute combine to form an associated molecule `X` is degree of association the Van't Hoff's factor 'I' is equal to:

If in a solvent, n simple molecules of solute combine of form an associated molecule, alpha is the degree of association, then Van't Hoff factor is equal to

How is degree of dissociation and degree of association are related with van't Hoff factor ?

For electrolytic solution, the Van't Hoff factor (i) is always equals to unity.

For electrolytic solution, the Van't Hoff factor (i) is always equals to unity.

For electrolytic solution, the Van't Hoff factor (i) is always equals to unity.

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

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