Question

A solute 'S' undergoes a reversible trimerisation 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. If the percent trimerisation of solute is ' X ', calculate $\frac{x}{10}$ .

Answer:

3.00

Solution:

$0.1 \times (1 - \frac{2 α}{3}) = 0.08 \Rightarrow α = 0.3$

​ 0.1 × ( 1 − 3 2 α ​ ) = 0.08 ​ ⇒ α = 0.3 ​
