According to Henry's law the partial pressure of the gas in vapour phase (p) is proportional to the mole fraction of the gas (x) in the solution . For different gases the correct statement about Henry's constant is

A

higher the value of `K_H` at a given pressure , higher is the solubility of the gas

B

higher the value of `K_H` at a given pressure , lower is the solubility of the gas

C

`K_H` is not a function of nature of gas

D

`K_H` value for all gases is same at a given pressure

Text Solution

Verified by Experts

The correct Answer is:
B
`p=K_Hx`. Higher the value of `K_H` at a given pressure, lower is the solubility of the gas in the liquid
