Question: Carbon dioxide is being absorbed in a strongly alkaline solution from a gas mixture containing 12% CO2(1), 22% N2(2) and 66% H2(3) Nitrogen and hydrogen

Carbon dioxide is being absorbed in a strongly alkaline solution from a gas mixture containing 12% CO2(1), 22% N2(2) and 66% H2(3) Nitrogen and hydrogen are virtually insoluble. Calculate the rate of absorption through a gas-film of 1.5 mm thickness if the ratio of volume fractions of N2 and H2 remains constant over the diffusion path. The temperature is 50C and the total pressure is 5 bar. Assume that CO2 reaching the solution is absorbed instantaneously
