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

    How is partial pressure of a gas related to its mole fraction?

    The relative lowering of vapour pressure is equal to the mole fraction of the non-volatile solute. This statement was given by

    According to Henry's law, the solubility of a gas in a given volume of liquid increases with increases in :

    The vapour pressure of a pure liquid A at 300 K is 150 torr. The vapour pressure of this liquid in a solution with a liquid Bis 105 torr. Calculate the mole fraction of A in the solution if the mixture obey's Raoult's law.

    State Henry's law correlating the pressure of a gas and its solubility in a solvent and mention two applications for the law.

    STATEMENT-1 : Solubility of a gas in a liquid solution is a function of the partial pressure of the gas. STATEMENT-2 : Mole fraction of the gas in a solution is proportional to the partial pressure of the gas. STATEMENT-3 : Higher the value of k_(H) at a given pressure, the lower is the solubility of the gas in the liquid.

    STATEMENT-1 : For solution of volatile liquids, the partial vapour pressure of each component in the solution is directly proportional to its mole fraction. STATEMENT-2 : Always there will be lowering of vapour pressure on addition of non-volatile solute to a solvent. STATEMENT-3 : If there is dissociation of non-volatile then the V.P. of solution increases.
