Consider the case in which liquid A evaporates and diffuses through stagnant gas B. The process is carried out at 25 °C and the total pressure 1 atm, calculate the molar flux when the level of a liquid A is 0.05 m below the top of the container. Assume that DAB-105 m²/s. The mole fraction of A at the gas-liquid interface is 0.2. At the top of the container, the mole fraction is 0.001. Determine convective mass transfer coefficient, ko and NA
