Sulfur dioxide (A) diffuses through a stagnant layer of air (B) of 2 cm thickness at 45°C and 1.2 bar total pressure. The partial pressures of SO2 on the two sides of the air layer are PAO 0.85 bar and PAt =0.15 bar, respectively. Considering Air is a non-diffusing component and Dso2-Air 3.5×10'm²/sec, calculate: - 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 SO, with respect to an observer moVing with thc mass average velocity.

Sulfur dioxide (A) diffuses through a stagnant layer of air (B) of 2 cm thickness at 45°C
and 1.2 bar total pressure. The partial pressures of SOz on the two sides of the air layer are
PAO
= 0.85 bar and PAL =0.15 bar, respectively. Considering Air is a non-diffusing
component and Dso2-Air= 3.5×10*m²/sec, calculate.
+ The molar flux of SO2
ii- The velocities of the individual components with respeet to a stationary observer.
i- The molar and the mass average velocities of the components
iv- The molar flux of SO: with respeet to an observer moving with the mass average
velocity.
