Pure B gas at 2 atm pressure is flowing over A liquid with a high flow rate, causing A to evaporate at the liquid surface. The vapor pressure of A at the liquid surface is 0.2 atm at 298 K. Given that the mass transfer coefficient ky' is 6.78x10-5 kmol/s.m2.mol fraction, calculate the evaporation rate of A and the mass transfer coefficients ky and kG.
