K _ H value for some gases at the same temperature ' T ' are given: array c|c gas & K _ H / k bar Ar & 40.3 CO ₂ & 1.67 HCHO & 1.83 10⁻⁵ CH ₄ & 0.413 array where K _ H is Henry's Law constant in water. The order of their solubility in water is :
Options
- AAr < CO ₂ < CH ₄ < HCHO
- BAr < CH ₄ < CO ₂ < HCHO
- CHCHO < CO ₂ < CH ₄ < Ar
- DHCHO < CH ₄ < CO ₂ < Ar
Correct answer
A. Ar < CO ₂ < CH ₄ < HCHO
Step-by-step solution
K _ H = Henry Law constant of gas in water, released to solubility as: Solubility of a gas 1 ~K _ H Value This means higher is the value of K _ H , lower will be the solubility of gas in water. Solubility order of given gas in water = HCHO > CH ₄> CO ₂> Ar
