Dissolved oxygen is being gassed off water using pure nitrogen gas as the sparger in a wetted wall column. At one point in the column, the oxygen content of the water is 6.3 mg/L. The liquid and gas side local mass transfer coefficients were determined as 0.0638 m/s and 0.0998 mol/m² -s-atm, respectively. If the Henry's Law constant for the system is 770 atm/M at 27.5°C and 1 atm, what percent of the resistance is offered by the gas phase? O 45.4% O 71.0 % O 56.5% 54.6 %
