The bulk concentrations of a solute at a section in a counter-current column are measured as Question I x=0,05 (liquid phase) and y=0.17 (gas phase). The individual mass transfer coefficients are k,a=2.9104 and ka=5104. The equilibrium relation can be approximated by the function (a) What is the direction of mass transfer? (gas to liquid or the reverse) (b) Calculate the overall transfer coefficients Ka and K ya. (c) What fraction of the mass transfer resistance oceurs in the liquid phase
