In case of association i (van’t Hoff factor) is given by
i = 1 – (1- 1/n)α, where
n= number of molecules associates = 4 (here),
α = fraction of molecules associates

i = 1 – (1- ¼)α = 1 – ¾ α
if α be 1 (complete association), then

i= 1 – ¾ = ¼

van`t hoff factor = Number of moles of particle after association / Number of moles of particles before associationTherefore : 4X ➡ X4 and hence van`t hoff factor = 1/4

Hello student

Hope it helps

Dear Student

In the case of association i (van’t Hoff factor) is given by
i = 1 – (1- 1/n)α
where n= number of molecules associates = 4 (Because of tetramerization)
α = fraction of molecules associates
i = 1 – (1- ¼)α = 1 – ¾ α
if α be 1 (complete association),
then i= 1 – ¾ =¼

I hope this answer will help you.
Thanks & Regards
