A solute 'A' undergoes association in a medium as nA leftharpoons An The degree of association is 'α ' , then van't Hoff factor may be give as (A) i=1-α  (B) i+1+(α /n) (C) i=(1 - α + (α /n)/1) (D) i = 1

In case of association, α and i can be related as follows α =(1 - i/1 - (1)n) So i=(1 - α + (α /n)/1)

Q. A solute 'A' undergoes association in a medium as

$n A ⇌ A_{n}$

The degree of association is $^{'} α^{'}$ , then van't Hoff factor may be give as

$i = 1 - α$

$i + 1 + \frac{α}{n}$

$i = \frac{1 - α + \frac{α}{n}}{1}$

i = 1

In case of association, $α$ and i can be related as follows

$α = \frac{1 - i}{1 - \frac{1}{n}}$

So $i = \frac{1 - α + \frac{α}{n}}{1}$

Q. A solute 'A' undergoes association in a medium as nA⇌An​ The degree of association is ′α′ , then van't Hoff factor may be give as

i=1−α

i+1+nα​

i=11−α+nα​​
