When a solute trimerises in a solvent then van't-Hoff factor `i`

Discuss the van't Hoff factor.

If van't Hoff factor i=1,then

van't Hoff equation is

The electrolyte solutions show abnormal colligative porperties.To account for this effect we define a quantity called the Van't Hoff factor given by i=("Actual number of particles in solution after dissociation")/("Number of formula units initially dissolved in solution") i=1 ("for non-electrolytes") igt1 ("for electrolytes, undergoing dissociation") ilt1 ("for solutes, undergoing association") Answer the following questions: certain substances trimerize when dissolved in a solvent A . The Van't Hoff factor i for the solutions is

Van't Hoff equation is

Acetic acid dimerises in benzene solution.The van't Hoff factor for the dimerisation of acetic acid is 0.8. The % of dimerisation of acetic acid is

If a solute undergoes dimerisation and trimerisation, the minimum values of the van't Hoff factors are

What is Van’t Hoff’s 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:
