 Okay. So this time we'll do an endothermic two-step reaction, so that means that the products or the reactants will be very low and the products will be higher than the reactants. Two steps means two pumps, right? We'll make the second step, the rate determining step. So when we do that, so what does that mean? The second pump is going to be bigger, right? So you guys probably already knew this, right? I don't know if I look like that. Okay, so from here to here, it's called the what? Delta G. Delta G. And is this going to be positive or negative? Positive. Positive. Why? Because A is lower than B, right? What's, so notice this one. EA1, right? Or Delta G double dagger one. It starts from A and goes up to TS1, okay? So that's one that people always, they always want to start it here for some reason. Okay, so don't do that. This, in this valley is called what? I or intermediate. And from the floor of that valley all the way to the top up here, it's going to be EA2, right? And this up here, TS2. Notice I can draw it like this, or I can even draw it like this. You should be able to figure it out, right? If I do that on the test, we should be able to draw this whole thing, okay? Can we go with that? Are there any questions? Could you change this to a two step endothermic reaction where the rate determining step was the first step? How would you do that? Do you have one bigger? Yeah, just go like this, okay? Maybe we'll draw that some other time, so. Can I kill it?
