12yr later u r a life saver m gonna younk this derivation nd write it in my Master degree exam Ps-studying this 3 hr befor exam u r life saver 😢

[@DEPHANPINHEIRO]

The best explanation yet !

[@jfdowd]

This is really quite an excellent explanation. Thank you.

[@emiliohernandez1571]

Enjoying the speed. Thanks!

[@rockinapond]

thank you! I've always heard that fugacity one of the hardest concepts to learn in chem e, but you've made it seem easy!

[@userr_aa]

Ikr... the words used in the lecture note is quite confusinggggg but thank God this video helps a lot!

[@jeremykinnear9786]

This really helped me. Thanks a lot!

[@takeoUup115]

I'm getting a way ahead of myself ,with barley a high-school understanding of physics ,this video is so above my Intellect. I am glad thought that you took the time to make this video, very likely i will come back to it in the future, Thanks.

[@mrxwerewolf1]

did you come back?

[@ogundokunpeter602]

🙃 u had to ask. I hope he did come come back tho

[@UliSwag]

Probably never made it past an intro to chemical engineering class 😹

[@kuntarinirahsilawati920]

Thank you very much! It really helps.

[@Casey-dy2oo]

SO helpful! Thank you

[@judyxia5350]

Amazing Video!!!!

[@jasondowd3099]

Perhaps the clearest explanation in existence.

[@lawlichin8502]

like this video~good understanding~~

Hi , please someone can help me ?

[@pabloalbarran7572]

I did not understand the criteria over which is established the mass transfer direction will ocurr in the opposite direction of what it would be expected. Could you expand a little bit on it? please.

[@ridhwanlawal2672]

This is based on the presumption that mass transfer should occur from a region with a higher concentration to another with a lower concentration

[@muhammadshehreyarkhan1851]

Both phases are not in equilibrium & common sense demands that the flow should be from higher concentration (liquid here) to low concentration (vapor) until equilibrium is established. However, in this specific case, the saturation pressure of vapor phase @ 45 C is more than that of liquid phase. That's why the concentration will shift the opposite way. That's what I have grasped.

[@donovanpaine3013]

Hi, for your ideal gas law, you have used PV=RT instead of PV=nRT, dont know if that is because your R isnt the universal constant and it equals of Ru/n.

[@donovanpaine3013]

Otherwise, helpful vid, thanks!

[@thegarcis401]

He used specific volume which is V/n, so he just incorporated the n with V.

[@monversity]

Thanks

[@prysrek8858]

I love fugacity

[@Khizar_Ansari]

What is this😭😭😭

[@pokemonjynx1019]

10 mins of explaining nothing...

[@tarikulhasan6199]

I was here for a definition, not a mathematical derivation. So disappointed. Secondly, use a point for god sake.

[@waseeintemas413]

He did define what fugacity is and used derivations to prove it. What's your problem?

[@tarikulhasan6199]

[@LABE2504]

@@tarikulhasan6199 For god sake, he gives a very clear definition of fugacity here.

[@tarikulhasan6199]

@@LABE2504 I am not here to argue with people. So kindly mind your own business for god sake. Btw, you can help me with the definition of fugacity.

[@challengepoker]

@@tarikulhasan6199 fugacity is the correction to be made when you study a real gas at conditions where the ideal gas law PV = RT doesn't work anymore.
