Chemical Engineering > GATE 2015 > Mass Transfer
Consider a steady state mass transfer process between well-mixed liquid and vapour phases of a binary mixture comprising of components A and B. The mole fractions of component A in the bulk liquid (xA) and bulk vapour (yA) phases are 0.36 and 0.16, respectively. The mass transfer coefficients for component A in liquid and vapour phases are 0.1 mol/(m2.s) and 0.05 mol/(m2.s), respectively. The vapour-liquid equilibrium can be approximated as yA* = 2xA for xA less than 0.4. The mole fraction of A in the liquid at the interface (up to two decimal places) is _______.

Correct : 0.22
