Main Difference – Henry’s Law vs Raoult’s Law

Both Henry’s law and Raoult’s law are two laws found in thermodynamics and describe the relationship between a solution and its vapor that is in equilibrium with each other. Henry’s law can be used to explain the dissolution of a gas in a liquid solvent such as water. Raoult’s law indicates the behavior of solvent in a solution that is in equilibrium with its vapor pressure. However, there are certain limitations when applying these laws for real solutions. The main difference between Henry’s Law and Raoult’s Law is that Henry’s law describes the behavior of solutes of a solution whereas Raoult’s law describes the behavior of solvent in a solution.

What is Henry’s Law

Henry’s law is a gas law that explains the dissolution of a gas in a liquid medium. This law states that the amount of gas that is dissolved in a liquid is directly proportional to the partial pressure of that gas that is in equilibrium with the liquid. This can be given in an equation as below.

[A(aq)] = kH.PA(g)

Where, [A(aq)] is the concentration of the gas A that is dissolved in the solution,

kH is Henry’s law constant

PA(g) is the partial pressure of A(g)

Henry’s law constant is a proportionality constant and is dependent on the type of solvent, solute, and the temperature. Therefore, for a particular gas, Henry’s law constant may vary at different temperatures. Therefore, when calculating the solubility of a gas in water, one should obtain the value of Henry’s law constant at that particular temperature.
