29.7 In a gas-liquid interface mass-transfer process, the bulk mole fraction composition of solute A in the inert carrier gas is 0.010, and the bulk mole fraction composition of solute A in the inert liquid solvent is 0.040. Equilibrium distribution data at the temperature and pressure of the process are provided below: XA 0.0000 0.0050 0.0100 0.0150 0.0200 0.0250 0.0300 0.0350 0.0400 YA 0.0000 0.0015 0.0030 0.0055 0.0090 0.0135 0.0200 0.0290 0.0425 a. If the liquid film mass-transfer coefficient k = 0.01 gmole/ m². s, and the gas film mass-transfer coefficient ky = 0.02 gmole/m² s, what is the overall mass-transfer coefficient based on the gas phase driving force, and the % resistance to mass-transfer in the gas phase?
