Question: The gas CO 2 is diffusing at steady state through a tube 0.20 m long having a diameter of 0.01 m and containing N 2

The gas CO2is diffusing at steady state through a tube 0.20 m long having a diameter of 0.01 m and containing N2at 298 K. The total pressure is constant at 101.32 kPa. The partial pressure of CO2at one end is 456 mmHg and 76 mmHg at the other end. The diffusivityDABof CO2in N2is 1.67 105m2/s at 298 K. Calculate the flux of CO2in (a) cgs and (b) SI units for equimolar counterdiffusion. Note: Gas constant = 82.057 cm3atm/mol K.
