A tube with an inside diameter of 1 cm and length of 30 cm is filled with air (B) and CO2 (A) at a total pressure and temperature of 1 atm and 3°C, respectively. If the partial pressure of CO2 is 0.75 atm at one end of the tube and 0.25 atm at the other end, find the rate of mass transfer of CO2 for the steady-state counter diffusion where NB = -0.55 NA (You can take gas constant (R) as 8314 m^3Pa/kgmol·K).
Can you provide a detailed step-by-step solution using mass transfer formulas?
