AI Thread Summary
Data on the osmotic pressure of NaCl solutions can be found in various online scientific databases and research articles. The van't Hoff equation describes the linear relationship at low concentrations, but comprehensive data from zero concentration to saturation is less common. Resources like the National Institutes of Health or academic journals may provide the needed information. Additionally, studies on seawater composition could offer insights into similar osmotic pressure behaviors. Accessing these sources will help clarify the relationship across the full concentration range.

Can anyone tell me about online source where I can find osmotic pressure vs concentration of NaCl solution. it obeys the linear relation of van't Hoff equation in low concentration solution, but I need the relation from zero concentration to saturation point.
It would be great if this relationship is also available for a solution has the same composition of sea water - except the water which is varying with the concentration.
Thank you!

Could be the answer is is worth Nobel prize.

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...
