Consider a closed system with water and NAPL. If liquid NAPL is present, then:

a.) Henry's Law governs the amount of NAPL that can dissolve in the water.

b.) The concentration of the NAPL in the aqueous phase is equal to the NAPL solubility constant

c.) The concentration of the NAPL in the aqueous phase is less than the NAPL solubility constant

d.) The NAPL phase floats on top of the water phase.
