Henry's Law at constant temperature states that
The solubility of gas in a liquid is directly proportional to the partial pressure of gas in solution.
Mole fraction of gas in solution is proportional to partial pressure of gas over solution
Partial pressure of gas in vapour phase is proportional to mole fraction of gas in solution
All of these
As learnt in
Henry's Law -
It decides the solubility of gases in liquids.
= mole fraction of gas in liquid.
= Partial pressure of gas over liquid surface.
-
Henry's law states that solubility of a gas in a liquid is directly proportional to partial pressure of gas. All the other options can be implied from above.
Option 1)
The solubility of gas in a liquid is directly proportional to the partial pressure of gas in solution.
This option is incorrect
Option 2)
Mole fraction of gas in solution is proportional to partial pressure of gas over solution
This option is incorrect
Option 3)
Partial pressure of gas in vapour phase is proportional to mole fraction of gas in solution
This option is incorrect
Option 4)
All of these
This option is correct
