AP EAPCET 2021 - 20th August Morning Shift | Liquid Solution Question 7 | Chemistry

If the $$K_{\mathrm{H}}$$ values for $$\operatorname{Ar}(g), \mathrm{CO}_2(g), \mathrm{HCHO}(g)$$ and $$\mathrm{CH}_4(\mathrm{~g})$$ respectively are $$40.39,1.67, 1.83 \times 10^{-5}$$ and $$0.413$$ , then identify the correct increasing order of their solubilities.

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

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

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

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