Stoichiometry
Pure aniline is evaporating through a stagnant air film of 1 mm thickness at 300 K and a total pressure of 100 KPa. The vapor pressure of aniline at 300 K is 0.1 KPa. The total molar concentration under these conditions is 40.1 mole/m³ . The diffusivity of aniline in air is 0.74xl0⁻⁵m²/s.The numerical value of mass transfer co-efficient is 7.4 x 10⁻³. The rate of evaporation of aniline is 2.97 x 10⁻⁴. Its units are

Mole/s
Mole/m² . s
Mole/cm². s
