Henry's law states that the
(A) Partial pressure of a component over a solution is proportional to its
mole fraction in the liquid
(B) Partial pressure of a component over a solution is proportional to the
mole fraction in the vapour
(C) Vapour pressure is equal to the product of the mole fraction and total
pressure
(D) Partial pressure is equal to the product of the mole fraction and total
pressure
