Which Gas Behaves Most Ideally: N2, CO, or H2?

Click For Summary
SUMMARY

The discussion centers on determining which gas among nitrogen (N2), carbon monoxide (CO), and hydrogen (H2) behaves most ideally. Participants conclude that hydrogen (H2) is expected to behave most ideally due to its small molecular size, although nitrogen (N2) is also considered a strong candidate. The van der Waals equation and its correction factors are suggested as tools for analyzing gas behavior, indicating that intermolecular forces and molecular size play crucial roles in ideal gas behavior.

PREREQUISITES
  • Understanding of ideal gas laws and behavior
  • Familiarity with molecular sizes and their impact on gas behavior
  • Knowledge of the van der Waals equation and its application
  • Basic concepts of intermolecular forces
NEXT STEPS
  • Research the van der Waals equation and its correction factors
  • Study the properties of gases and their molecular sizes
  • Explore the concept of ideal gas behavior in different conditions
  • Investigate the differences between real gases and ideal gases
USEFUL FOR

Chemistry students, educators, and anyone interested in gas behavior and thermodynamics will benefit from this discussion.

Homework Statement



In general, which of the following gases would you expect to behave the most ideally?
a) N_2
b) CO
c) H_2


Homework Equations



N/A

The Attempt at a Solution



Okay, so I know that CO would definitely not behave the most ideally. I tried looking this up on the internet and I read that He would act the most ideally because it is the smallest molecule, and seeing how hydrogen is the next smallest, I think the answer is c) hydrogen gas but then I saw on another site that they said that nitrogen gas was the most ideal...so I am slightly confused. Anybody can shed some light please? Any help is appreciated.

I wonder if the van der Waals equation and the correction factors could be used to rank the ideality of a particular gas?
