Sulfur dioxide (A) diffuses through a stagnant layer of air (B) of 2 cm thickness at 45oC and 1.2 bar total pressure. The partial pressures of SO2 on the two sides of the air layer are PA0 = 0.85 bar and PAL =0.15 bar, respectively. Considering Air is a non-diffusing component and DSO2-Air = 3.5×10-5 m2/sec, calculate: i- The molar flux of SO2 ii- The velocities of the individual components with respect to a stationary observer. iii- The molar and the mass average velocities of the components. iv- The molar flux of SO2 with respect to an observer moving with the mass average velocity.

Question
Sulfur dioxide (A) diffuses through a stagnant layer of air (B) of 2 cm thickness at 45oC and 1.2 bar total pressure. The partial pressures of SO2 on the two sides of the air layer are PA0 = 0.85 bar and PAL =0.15 bar, respectively. Considering Air is a non-diffusing component and DSO2-Air = 3.5×10-5 m2/sec, calculate:
i- The molar flux of SO2
ii- The velocities of the individual components with respect to a stationary observer.
iii- The molar and the mass average velocities of the components.
iv- The molar flux of SO2 with respect to an observer moving with the mass average velocity.
