Homework Statement Adsorption, coagulation, and flocculation are all important processes to remove or separate target substances from mixtures. In these processes, we can observe the spontaneous decrease of entropy.; can we therefore conclude that the second law of thermodynamics doesn't always...

Hi there, sorry for the late reply. Thank you for confirming my solution; I was starting to wonder if there was another shortcut that involves a...

Homework Statement Calculate the molecular diameter of hydrogen, assuming the spherical shape on the basis of van der Waals coefficients. Van der Waals Coefficients for hydrogen a = 0.244 atm L2.mol-2 b*103 = 26.6 L.mol-1 Homework...

Thanks anyway!

Hello Chet, thank you for your reply! I have in fact managed to solve the problem using the barometric formula (if my calculations are correct P=533.04 with sea level atmospheric pressure set at 100kPa). However, our teacher instructed us to utilize Brownian motion theory; I'm not too familiar...

Hello all! Can you please provide some guidance with this problem? 1. Homework Statement Calculate the air pressure at 3000m above sea level assuming that the molecular weight of air is 29 and the ambient temperature is constant against height. Homework Equations Stokes-Einstein equation. In...
