- Aincreased vapour pressure, increased boiling point
- Bincreased vapour pressure, decreased boiling point
- Cdecreased vapour pressure, decreased boiling point
- ✓decreased vapour pressure, increased boiling point
$ \mathrm{P}_{\mathrm{T}}<\mathrm{P}_{\mathrm{A}^0} \mathrm{X}_{\mathrm{A}} +\mathrm{P}_{\mathrm{B}^0} \mathrm{X}_{\mathrm{B}} $
$ \mathrm{P}_{\mathrm{A}}<\mathrm{P}_{\mathrm{A}^0} \mathrm{X}_{\mathrm{A}} $
$ \mathrm{P}_{\mathrm{B}}<\mathrm{P}_{\mathrm{B}^0} \mathrm{X}_{\mathrm{B}} $
If vapour pressure decreases so boiling point increases.

$\mathrm{Zn}\left|\mathrm{Zn}^{2+}(\mathrm{aq}),(1 \mathrm{M}) \| \mathrm{Fe}^{3+}(\mathrm{aq}), \mathrm{Fe}^{2+}(\mathrm{aq})\right| \mathrm{Pt}(\mathrm{s})$
The fraction of total iron present as $\mathrm{Fe}^{3+}$ ion at the cell potential of $1.500\, \mathrm{~V}$ is $\mathrm{X} \times 10^{-2}$. The value of $x$ is $.....$ (Nearest integer).
$\left(\right.$ Given $\left.E_{\mathrm{Fe}^{3+} / \mathrm{Fe}^{2+}}^{0}=0.77\, \mathrm{~V}, \mathrm{E}_{\mathrm{Zn}^{2+} / \mathrm{Zn}}^{0}=-0.76 \,\mathrm{~V}\right)$
