Good morning/afternoon/evening. Regarding the mole fraction of component 1, x1, at 5:28, should we use the x1 in Alpha phase or the x1 in Beta phase?

got anything showing how to use the lewis fugacity rule for a vapor mixture?

[@samtellbar3180]

So what is the direction of mass transfer for component 1?

Thanks

🎯 Key Takeaways for quick navigation: 00:06 📚 Fugacity in mixtures involves considering multi-component systems with different mole fractions in alpha and beta phases. 01:01 🔬 The direction of mass transfer is determined by the chemical potential (or fugacity) of component one in the alpha and beta phases. 02:22 📊 For an ideal gas mixture, the fugacity of a component is determined by its mole fraction and total pressure in the alpha phase. 03:15 💧 In an ideal liquid phase, fugacity is calculated relative to the saturation pressure of the pure component in the beta phase. 04:11 📖 Raoult's Law defines equilibrium in an ideal solution, stating that fugacity in the alpha and beta phases must be equal. 05:02 🔄 Changing variables like pressure and temperature affect fugacity differently in gas and liquid phases. 06:18 🌡️ Saturation pressure increases with temperature, leading to higher fugacity in the liquid phase. 07:44 📏 Fugacity is an intensive variable, meaning it's independent of the quantity of the phase. Equilibrium concentrations (mole fractions) are crucial. Made with HARPA AI
