Question about osmotic pressure of blood plasma

AI Thread Summary
The discussion revolves around determining the osmotic pressure of blood plasma required for water absorption from the interstitium to the capillary bed. The options provided range from less than 20 mmHg to greater than 21 mmHg, with a specific focus on whether the correct answer is 21 mmHg. The poster expresses uncertainty about their reasoning and seeks clarification on their thought process. There is a lack of responses or confirmations from other participants, indicating a possible need for more engagement on the topic. The inquiry highlights the complexities of osmotic pressure in physiological contexts.

Homework Statement



The osmotic pressure (π) of the blood plasma necessary to induce absorption of water from interstitium (outside) to the capillary bed under circumstances shown on the picture (attached) has to be
a. Less than 20 mmHg
b. Between -1 and 20 mmHg
c. Equal to 21 mmHg
d. Greater than 21 mmHg

Homework Equations

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...
