QNEET-2022-Ch-483: NEET 2022 Chemistry - Class 12 NEET-2022-Ch-483 Solution: \(K_H\) value for some gases at the same temperature 'T' are…
value for some gases at the same temperature 'T' are given: Gas Ar 40.3 1.67 HCHO 0.413 where is Henry's Law constant in water. The order of their solubility in water is: HCHO < < < Ar Ar < < < HCHO Ar < < < HCHO HCHO < < < Ar
Multiple Choice Options
- A HCHO < CH 4 < CO 2 < Ar
- B Ar < CO 2 < CH 4 < HCHO
- C Ar < CH 4 < CO 2 < HCHO
- D HCHO < CO 2 < CH 4 < Ar
Step-by-Step Verified Solution
According to Henry's Law,
p = K H x
Where 'p' is partial pressure of gas in vapour phase.
K H is Henry's Law constant.
'x' is mole fraction of gas in liquid.
Higher the value of K H at a given pressure, lower is the solubility of the gas in the liquid.
_ Solubility : Ar < CO 2 < CH 4 < HCHO
