Chemistry - Liquid Solution Question with Solution | TestHub

$\mathrm{\Delta }{\mathrm{T}}_{\mathrm{b}}={\mathrm{K}}_{\mathrm{b}}\left(\mathrm{i}\mathrm{m}\right)$.
The value of (im) is maximum for 0.2 M$\mathrm{N}{\mathrm{a}}_2\mathrm{C}{\mathrm{O}}_3(\mathrm{i}=3).$
Hence,$\mathrm{\Delta }{\mathrm{T}}_{\mathrm{b}}$is maximum for 0.2 M$\mathrm{N}{\mathrm{a}}_2\mathrm{C}{\mathrm{O}}_3$. Consequently, 0.2 M$\mathrm{N}{\mathrm{a}}_2\mathrm{C}{\mathrm{O}}_3$has maximum boiling point.
