Two bulbs are connected by a straight tube, 0.001 m in diameter and 0.35 m in length. Initially the bulb at end 1 contains H, and the bulb at end 2 contains C02. The pressure and temperature are maintained constant at 25°C and 1 atm. At a certain time after allowing equimolar diffusion to occur between the two bulbs the partial pressure of H2 is 90 mmHg at one end and 30 mmHg at the other end, Estimate the diffusivity (DAB) for the following conditions by the method of Fuller et al. (a) Calculate the flux at 298 K for H2 (b) Repeat at 298 K but for a total pressure of 4.0 atm. The partial pressure of H2 remains at 90 and 30 mm Hg. Does the flux change?

Question
Two bulbs are connected by a straight tube, 0.001 m in diameter and 0.35 m in length. Initially the bulb at end 1 contains H2 and the bulb at end 2 contains CO2. The pressure and temperature are maintained constant at 25°C and 1 atm. At a certain time after allowing equimolar diffusion to occur between the two bulbs the partial pressure of H2 is 90 mmHg at one end and 30 mmHg at the other end, Estimate the diffusivity (DAB) for the following conditions by the method of Fuller et al. (a) Calculate the flux at 298 K for H2 (b) Repeat at 298 K but for a total pressure of 4.0 atm. The partial pressure of H2 remains at 90 and 30 mm Hg. Does the flux change?
