The interfacial mass transfer coefficient (in mol m-2 s-1) for the gas side is 0.1 and for the liquid side is 3. The equilibrium relationship is y* = 2x, where x and y* are mole fractions of the solute in the liquid and gas phases, respectively. shortage diagram https://harringtonconsultinggroup.com
