What will be the equilibrium pressure in the vessel? b. The vessel of part (a) develops a small leak so that air enters the vessel (because of the pres- sure difference), but no water leaves. What will be the pressure in the vessel at equilibrium, the mole fraction of water in air, and the mole frac- tions of nitrogen and oxygen in the water? Data: The Henry's law constants for oxygen and nitrogen in water at 25°C are bar Ho, = 4.35 x 10*. mole fraction and bar Hy3 = 8.48 × 10* mole fraction (Hint: The Henry's constants are so large that the mole fractions of oxygen and nitrogen in the water will be small.)
