Compress air vessel has a volume of 10 ft3 .Cooling coils holds

AI Thread Summary
The discussion revolves around calculating the pressure increase in a compressed air vessel with a volume of 10 ft³, maintained at 68°F, and currently at 100 psi, with air flowing in at 10 lbm/hr. The user has converted the mass flow rate to a molar flow rate and applied the ideal gas equation to determine the pressure change in psi/hr. Participants are encouraged to share their calculations and methodologies to verify the results. The conversation emphasizes the importance of showing detailed steps in the solution process. Overall, the thread seeks collaborative problem-solving in thermodynamics.

Homework Statement


Compress air vessel has a volume of 10 ft3 .Cooling coils holds its temperature at 68F. The pressure now in the vessel is 100 psi. Air is flowing in at the rate of 10 lbm/hr.How fast is the pressure increasing?






The Attempt at a Solution


What I have done is that I have converted mass flow rate into molar flow rate and by using ideal gas equation i found the pressure which has the unit of psi/hr...

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...
