(4 pts) When we considered the two-bulb problem, we used an integral mole balance to analyze the tubes. Repeat this analysis beginning with a differential mole balance, tci=Ni+Si and show that you obtain the same answer for the mole fraction profile. Clearly state/justify your assumptions and show your work! 2. (2 pts) When we analyzed the beaker problem, we said that NA and NB were both constant, and then we reasoned that NB=0 (unimolecular diffusion). Starting with a differential mole balance, show that Ni is constant. Then justify why that constant should be zero for the case of the air, NB=0
