Question
A solute′S′ undergoes a reversible trimerization when dissolved in a certain solvent. The boiling point elevation of its 0.1 molal solution was found to be identical to the boiling point elevation in case of a 0.08 molal solution of a solute which neither undergoes association nor dissociation. To what percent had the solute ′S′ undergone trimerization?
Options
A.30%
B.40%
C.50%
D.60%
Solution
3S ⇋ S3
1-α α/3 ⇒ i = 1 -
Now 0.1
= 0.08
⇒ α = 0.3. Hence 30% trimerization.
