Henry’s law states that “the partial pressure of the gas in vapour phase (p) is proportional to the mole fraction of the gas (x) in the solution” and is expressed as:

P =K_H​ X   

Here K_H is Henry’s law constant.

Different gases have different K_H​ values at the same temperature. This suggests that K_H​ is a function of the nature of the gas.

K_H​ $\propto$P

More is K_H​ less is solubility, lesser solubility is at higher temperature.

So, more is the temperature, more is the K_H​.
