You are the best sir. You answered all of my questions and fully explained in a proper channel. Loved it.
Fantastic video! Actually actually understood everything you said and did. You made a very complex topic very simple.
Awesome video!! Really helped a lot for my exams :)
Awesome videos thanks you for the help, the subject seems clear and simple
Excellent video!
thanks people, i m considering working your school from now on
thanks alot
How did you calculate the % of change in gas flow (2:45)?
Isn't 1640 atm/mole frac the Henry's Law constant for nitrogen, not carbon dioxide?
Sounds like Jim from the Office
You Mean Jimothy?
Just one question to ask if you are available. What if there are two gases absorbing? Should we include less absorbing gas in the carrier gas or exclude it?
Hi, I know this is two years after your original comment but your question is interesting. Theoretically I see two options to solve your problem. Define the gasses as a mixture, and use a mixture property law for the he ry constant which is after all a function of the composition of the mixture by way of the pressure and temperature as well ass the ratio of components, this can only know if you know the ratios of the two absorbing gases though. The second option would be to assume an arithmetic mean, and treat the 2 gases as 2 pure component systems, and then just add the results you obtain for both. I think the forst option would be more accurate though.
