cheers for this derivation - was just given to us in the lecture notes with no explanation about where it came from, so this has really helped to understand it!
For my Physical Chemistry exam, I need to link the Gibbs Adsorption isotherm with the lattice model. This video made me understood the principles well, but I have some problems deriving a solution to find the physicochemical equilibrium at the surface. Help would be useful :D Watch 9:26 find Mewtwo.
You are welcome; I am happy it is useful. We can put the Gibbs dividing surface anywhere we want. The most common convention is to put the dividing surface at the location that would give a zero surface excess of solvent.
We take it to be zero to define the interface where no solvent molecule is present. This very definition allows us to ascribe positive negative or zero value to surface excess of any other component I. E. The solutes.
Your videos are awesome. Makes my uni tuition look like a waste of money. Please keep it up. You're doing great work!

Thanks for the video. It's really easy to digest

Wow dude, thanks a lot. I'm studying this from Levine but sometimes it's tough to follow.
Thanks for the video! Why is the surface excess of the solvent equals zero?
