**H1.** Two identical large glass bulbs are filled with gases and connected by a capillary tube that is Δ = 0.0100 m long. Bulb 1 at z = 0 contains the following mole fractions: y_{air} = 0.520, y_{H2} = 0.480, and y_{NH3} = 0.000. Bulb 2 at z = Δ contains y_{air} = 0.540, y_{H2} = 0.000, and y_{NH3} = 0.460. Since the bulbs are quite large, operation is at pseudo- (or quasi-) steady state. [In other words, assume the mole fractions at the boundaries are constant (e.g., y_{air} = 0.520 at z = 0 and y_{air} = 0.540 at z = Δ so that Δy_{air} = 0.02) and the total flux of air + hydrogen + ammonia is zero.] The pressure is uniform at 2.00 atm, and the temperature is uniform at 273 K. Diffusivity values can be determined from Table 15-1. Assume the gases ...
