$\mathrm{HX}\rightleftharpoons {\mathrm{H}}^{+}+{\mathrm{X}}^{-}(\mathrm{n}=2)$

$\mathrm{i}=1+\alpha (\mathrm{n}-1)$

$=1+0.2(2-1)$

$\mathrm{i}=1.2$

$\Delta {\mathrm{T}}_{\mathrm{f}}={\mathrm{ik}}_{\mathrm{f}}\mathrm{m}$

${\mathrm{T}}_{\mathrm{f}}^{\circ }-{\mathrm{T}}_{\mathrm{fs}}=1.2\times 1.86\times 0.2$

$273-{\mathrm{T}}_{\mathrm{fs}}=.4464$

${\mathrm{T}}_{\mathrm{fs}}=273-.4464$ $=272.5536\mathrm{K}$
