Question

$K_H$ value for Ar (g), CO₂ (g), HCHO (g) and CH₄ (g) are 40.39, 1.67, 1.83 × 10⁻⁵ and 0.413 respectively. Arrange these gases in the order of their increasing solubility.
(a) HCHO < CH₄ < CO₂ < Ar
(b) HCHO < CO₂ < CH₄ < Ar
(c) Ar < CO₂ < CH₄ < HCHO
(d) Ar < CH₄ < CO₂ < HCHO

Answer 1

option C is correct

because Kh value increases then solubility in decreases
