AI Thread Summary
Hyperventilation leads to a decrease in carbon dioxide (CO2) levels in the blood. The discussion centers on whether this decrease occurs in arterial or venous blood. It is suggested that arterial PCO2 decreases due to the expulsion of CO2 during hyperventilation. The participants express uncertainty but agree that the arterial CO2 is likely affected more significantly. Clarification on the specific changes in venous PCO2 remains less clear.

I know that when you hyperventilate, the Pco2 in blood decreases... but is it the venous or arterial PCo2 that's decreasing?
Can someone please clarify this?
Thank you!

I was initially thinking arterial CO2 because after you blow a lot of it out through hyperventilating, less CO2 would be left to go to the body... but I'm not exactly sure :S

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...
