AI Thread Summary
The discussion revolves around calculating the amount of oxygen absorbed by blood in the lungs per minute. Given that 100 ml of lung vein blood contains 14 ml of O2, the calculation for 70 ml of blood yields approximately 0.98 ml of O2. With the heart beating 70 times per minute, the total O2 absorption would be 68.6 ml. However, there is a suggestion to double-check the calculation of x for accuracy. The overall focus is on ensuring correct proportional reasoning in the oxygen absorption calculation.

100 ml blood of lung vein contains 14 ml O2. The volume of blood in the left ventricle is 70 ml. Find the amount of O2 the blood absorbs in the lung for a minute.
Here's what I did
100ml blood -> 14 ml O2

70 ml blood -> x

x=0.98 ml O2

The heart beats 70 times
So 0.98*70=68.6 ml.
Is this solution right?

If you were trying to solve the proportion problem

##\frac{14\, ml\, O_2}{100\, ml\, blood} = \frac{x\, ml\, O_2}{70\, ml\, blood}##

You might want to check your calculation of x again.
 
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...
