Passage / Comprehension

A dilute solution contains 'x' moles of solute A in 1 kg of solvent with molal elevation constant K_b . The solute dimerises in the solution according to the following equation. The degree of association is (α).

2A ⇌ A₂

The degree of association is equal to :

Options:

Answer:

Solution:

$Δ T_{b} = [1 + (\frac{1}{2} - 1) α] K_{b} x$

$α = \frac{2 ( K _{b} \cdot x - Δ T _{b} )}{K _{b} \cdot x}$
