Hello everyone, i need to calculate the activity coefficient š¯›¾š¯‘– in order to calculate the mole fraction of a component in vapour phase from a given mole fraction of the component in its liquid phase using Raoult's law. I have found that for multi-component droplets, many literature has suggested to compute the value of š¯›¾š¯‘– using UNIFAC method. UNIFAC method itself is computationally heavy and may not be possible to implement the entire method in the actual model for multi-component droplet evaporation. Is there any other analytical equation for calculating the activity coefficient which will be possible to implement in the model for multi-component droplet evaporation?
Have a nice weekend!

For Raoult's equilibrium law (REL) gamma=1. The modified REL uses gamma different of 1.
Junior Lorenzo Llanes No i haven't. Can you please shed more light on that topic? Would be happy to know more about it. Thanks for replying
Hello Kapil Jaiswal,
I guess you are trying to do some kind of VLE calculations, so I recommend the book below.

Best,
did you find the way to calculate activity coefficient? I want to learn about that
