Effect of Henry's Law Constant ($$K_H$$)

$$p = K_H \cdot x \quad \implies \quad x \propto \frac{1}{K_H} \quad (\text{at constant } p)$$

$$\text{Temperature } \uparrow \quad \implies \quad K_H \uparrow \quad \implies \quad \text{Solubility } (x) \downarrow$$

Concept: $$K_H$$ depends on the nature of the gas, nature of the solvent, and temperature.

Notation & Key Points:

• Higher $$K_H$$ value at a given pressure indicates lower solubility of the gas in the liquid.
• Gases are less soluble in liquids at higher temperatures.
