Question

For p=K$_H$​x, here K$_H$​ is:

• A. Cryoscopic constant
• B. Henry’s Law constant
• C. Boyle’s constant
• D. Rate constant

Answer 1

The Correct Option is B

K$_H$ is Henry’s Law constant, describing the relationship between the solubility of a gas in a liquid and the partial pressure of the gas.

Answer 2

K_H is the Henry’s Law constant, which describes the relationship between the solubility of a gas in a liquid and the partial pressure of the gas above the liquid. Henry's Law states that, at a constant temperature, the amount of gas that dissolves in a liquid is directly proportional to the partial pressure of that gas.

Mathematically, this relationship is represented as:
C = K_H * P
where:

• C is the concentration of the dissolved gas in the liquid (mol/L),
• P is the partial pressure of the gas (atm),
• K_H is the Henry’s Law constant (mol/L·atm).

Henry’s Law constant is crucial in understanding phenomena such as gas exchange in biological systems, the carbonation of soft drinks, and the behavior of gases in natural water bodies. It can vary with temperature, as higher temperatures generally reduce the solubility of gases in liquids. Therefore, knowing the value of K_H is important for predicting how gases behave when in contact with liquids.
