Fugacities of Mixtures: Summary
Key points from this module:
- Fugacity is an intensive variable, so it does not depend on the amount of the phase.
- When phases are in equilbrium, the fugacity of component 1 is the same in each phase, the fugacity of component 2 is the same in each phase, etc. .
- For an ideal gas mixture, the fugacity of each component is equal to its partial pressure.
- For an ideal liquid, the fugacity of each component is its mole fraction times its saturation pressure.
From studying this module, you should now be able to:
- Determine which component has a higher fugacity.
- Determine the fugacity of each component.
- Draw a fugacity versus temperature graph for a binary mixture.
