The Henry's law constant $$(\mathrm{K}_{\mathrm{H}})$$ values of three gases $$(\mathrm{A}, \mathrm{B}, \mathrm{C})$$ in water are $$145, 2 \times 10^{-5}$$ and $$35 \mathrm{~kbar}$$ respectively. The solubility of these gases in water follow the order:
The plot of osmotic pressure (П) vs concentration $$(\mathrm{mol} \mathrm{~L}^{-1})$$ for a solution gives a straight line with slope $$25.73 \mathrm{~L} \mathrm{~bar} \mathrm{~mol}^{-1}$$. The temperature at which the osmotic pressure measurement is done is
(Use $$\mathrm{R}=0.083 \mathrm{~L} \mathrm{~bar} \mathrm{~mol}^{-1} \mathrm{~K}^{-1}$$)
Which amongst the following aqueous solution of electrolytes will have minimum elevation in boiling point? Choose the correct option :-
KH value for some gases at the same temperature 'T' are given :
| Gas | K$$_H$$/k bar |
|---|---|
| Ar | 40.3 |
| CO$$_2$$ | 1.67 |
| HCHO | 1.83 $$\times$$ 10$$^{ - 5}$$ |
| CH$$_4$$ | 0.413 |
where KH is Henry's Law constant in water. The order of their solubility in water is :
