MCQ (Single Correct Answer)

-1

K_H 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 K_H is Henry's Law constant in water. The order of their solubility in water is :

HCHO < CH₄ < CO₂ < Ar

Ar < CO₂ < CH₄ < HCHO

Ar < CH₄ < CO₂ < HCHO

HCHO < CO₂ < CH₄ < Ar
