Real Gas Equations of State

[@ninaciriello8346]

Thank you! My professor went on and on about how these were derived, but never really explained what the adjustments were for or why they were important. This is great, I really appreciate your videos!

Could I use the virial equation for 3 individual gases at constant pressure and temperature and then add the pressures together?

[@PhysicalChemistry]

(I'm assuming you meant to say use the virial equation at a particular **volume** and temperature.) You can do that, and it will be an approximation to the correct value (as any of these models are). If the accuracy of the virial equation is good enough for each of your 3 gases under the desired conditions, then it'll remain a good approximation if you sum the partial pressures together.

Yes volume! Thanks so much

You're so welcome!

No real gas, sir. Gases are all ideal gases. See DOI: 10.26434/chemrxiv-2022-5m718-v3
