large dry air is flowing over a surface from which benzene is evaporating with 1 atm absolute pressure as total pressure. The partial pressure of benzene at the surface is the vapor pressure at 298 K which is (0.42 atm). The Ke has been estimated to be (6.5*10 kmol / s.m. mol vol.). Calculate the vaporizing rate benzene, and the individual mass transfer coefficient Ky? (R=0.000082)

Question
large dry air is flowing over a surface from which benzene is evaporating with 1 atm absolute
pressure as total pressure. The partial pressure of benzene at the surface is the vapor pressure at
298 K which is (0.42 atm). The Ke has been estimated to be (6.5*10s kmol / s.m'. mol vol.).
Calculate the vaporizing rate benzene, and the individual mass transfer coefficient Ky?
