A large volume of pure gas B at 2 atm pressure is flowing over a piece of blotting paper from which pure A is vaporizing. Liquid A completely wets the surface of the paper, so the partial pressure of A at the surface is the vapor pressure at 298 K, which is 0.20 atm. The ky has been estimated to be 6.78x105 kmol/m².s.mole fraction. Calculate NA (the vaporization flux) and the value of ky and KG.
