Temperature-Pressure
Thread Content
Given the molar fractions of a mixture and the pressure-temperature relationships of the pure components, how can one calculate the pressure-temperature relationship for the mixture?；
Chapter 1 or Chapter 2 of Thermodynamics (Chen Xinzhi’s Chapter 1 is an introduction). You’ll know after reading it.
It depends on whether to treat it as a real fluid or an ideal gas; if it’s an ideal gas, the ideal gas equation can be used, but if it’s a real fluid, things get more complicated. It’s better to consult chemical thermodynamics in such cases
