AI Thread Summary

Purifying air from carbon dioxide is essential in large-scale nitrogen production to prevent the formation of solid CO2, which can occur at around -80°C. This solid can obstruct equipment and hinder the efficiency of the nitrogen extraction process. Additionally, CO2 can react with other components during the liquefaction process, leading to potential contamination. Drying the air is also necessary to remove moisture, which can cause similar issues. Effective purification ensures optimal operation and product quality in nitrogen production.

In large scale preparation of nitrogen from liquefied air why do we purify the air from carbon dioxide ?
what problem does it create?
I would be happy if anyone replies.
Thank you!

For the same reason we first dry it out

Thread 'Confusion regarding a chemical kinetics problem'

TL;DR Summary: cannot find out error in solution proposed. [![question with rate laws][1]][1] Now the rate law for the reaction (i.e reaction rate) can be written as: $$ R= k[N_2O_5] $$ my main question is, WHAT is this reaction equal to? what I mean here is, whether $$k[N_2O_5]= -d[N_2O_5]/dt$$ or is it $$k[N_2O_5]= -1/2 \frac{d}{dt} [N_2O_5] $$ ? The latter seems to be more apt, as the reaction rate must be -1/2 (disappearance rate of N2O5), which adheres to the stoichiometry of the...

Thread 'Prove that evolution is constant (Provide at least two arguments to support your position)'

I don't get how to argue it. i can prove: evolution is the ability to adapt, whether it's progression or regression from some point of view, so if evolution is not constant then animal generations couldn`t stay alive for a big amount of time because when climate is changing this generations die. but they dont. so evolution is constant. but its not an argument, right? how to fing arguments when i only prove it.. analytically, i guess it called that (this is indirectly related to biology, im...
