Q1(a) In an air-carbon dioxide mixture at 298 K and 202.6 kPa, the concentration of CO2 at two planes (3 mm) apart are 15 mole% and 25 mole%. The diffusivity of CO2 in air at 298 K and 202.6 kPa is 8.2*10-6 m/s. (0) Calculate the molar flux of CO2 at steady state for equimolar counter diffusion (ii) Calculate the flux of CO2 at steady state through stagnant air. (iii) Compare the molar flux of CO2 for equimolar diffusion with stagnant diffusion and justify your answer. [6] [6] [8]
