entropy of mixing

I add a little bit of inert gas, there's a little bit more entropy of mixing.

The decrease of partial entropy of mixing indicates the existence of strong interaction energy between the components exists.

If I have nothing, if I have no A here, up here and just the inert gas, then there's no entropy of mixing.

Without entropy of mixing, we would be sitting on this curve here.

D Because if I have equal amounts of A, B, C, and D, that's a lot of entropy of mixing there.

But the entropy of mixing is causing my initial state and my final state to go down.

Without entropy of mixing, then everything would go directly to the products.

Specifically, how entropy of mixing really becomes key to equilibrium.

So now I've got the entropy of mixing even in a condensed phase the liquid.

Entropy of mixing was responsible for equilibrium.

Because you've got entropy of mixing happening in all of this.

The entropy of mixing of reactants and products wasn't there.

So entropy of mixing is really super important.

And the entropy of mixing was really super important.

If entropy of mixing wasn't there, I would start from up here.

What's the magic word? Entropy of mixing, right.

So entropy of mixing here is driving this positive slope.

All driven by entropy of mixing.

Entropy of mixing comes in here.

Right. There's more entropy of mixing if you've got a mixture in the liquid than if you have a pure gas up there.

Let's now look at the entropy of mixing.

So we can just explicitly calculate the entropy of mixing.

So that's our entropy of mixing.
