.derive henry's law.

Answer 1

Henry's law is a gas law that states that the amount of dissolved gas is proportional to its partial pressure in the gas phase. The proportionality factor is called the Henry's law constant.

Answer 2

The Henry’s law constant is the expression for equilibrium distribution of a compound between water and gaseous phase denoted by KH. It indicates the volatility of the compound.

The mathematical expression for Henry’s law is given by

Where,

C is the solubility of the gas at a fixed temperature in a solvent (units in M or ml gas/L).

 is the Henry’s law constant (units in M/atm)

 is the partial pressure of the gas (units in Atm)
