Question

K_H value for $$\mathrm{Ar}(\mathrm{g})$$, $$\mathrm{CO}{\phantom{A}}_2(\mathrm{g})$$, $$\mathrm{HCHO}(\mathrm{g})$$ and $$\mathrm{CH}{\phantom{A}}_4(\mathrm{g})$$ are 40.39, 1.67, 1.83 × 10^–5 and 0.413 respectively. Arrange these gases in the order of their increasing solubility.

पर्याय

• $$\mathrm{HCHO}<\mathrm{CH}{\phantom{A}}_4<\mathrm{CO}{\phantom{A}}_2<\mathrm{Ar}$$

• $$\mathrm{HCHO}<\mathrm{CO}{\phantom{A}}_2<\mathrm{CH}{\phantom{A}}_4<\mathrm{Ar}$$

• $$\mathrm{Ar}<\mathrm{CO}{\phantom{A}}_2<\mathrm{CH}{\phantom{A}}_4<\mathrm{HCHO}$$

• $$\mathrm{Ar}<\mathrm{CH}{\phantom{A}}_4<\mathrm{CO}{\phantom{A}}_2<\mathrm{HCHO}$$

Answer 1

$$\mathrm{Ar}<\mathrm{CO}{\phantom{A}}_2<\mathrm{CH}{\phantom{A}}_4<\mathrm{HCHO}$$

Explanation:

The higher the value of K_H, the lower is the solubility of the gas in the liquid. Hence the order of increasing solubility of the gases will be $$\mathrm{Ar}<\mathrm{CO}{\phantom{A}}_2<\mathrm{CH}{\phantom{A}}_4<\mathrm{HCHO}$$
