Okay, so for this reaction, you're given the following reaction coordinate diagram. Uh I apologize. It's not drawn as nicely as it's in the book. And but from this, you want to answer a few questions. So the first one, in part a asks you how many intermediates there are. So remember that intermediates are going to be at the bottom of the well. So you have A is going to be your reactant, D. Is your products, B would be intermediate one and see would be intermediate two. So in this one you would have to intermediates which are I one and I too, or rather B and C. For the number of transition states, you're looking at these structures here. So you have delta G one, delta G, double dagger, two delta G three, double dagger. So in this case you have three transition states which are delta G double diaper. In this reaction, your fastest step is going to have your lowest transition state energy. And so when you measure this, you want to look at the difference in energy between the reaction in the transition state, right? So if you go from here to hear and then here to here. So your fastest step is going to be your smallest free energy of activation, which is going to be step C to D. For part D. You want to look at whether A. Or D. Is going to be more stable. So if we say that We set some type of zero point energy. Now you can see that A is higher in energy than D. So if something is more stable it has a lower energy, so D is going to be more stable. We just move this down a little bit. The next question wants to know the rate determining step and what is going to be the reactant of the rate determining step. And so your rate determining step is going to be your largest delta G. Now this isn't drawn as nicely as in the book, um but if you look delta G two, so your RDS is going to be, you're this delta G double dagger to the structure here. Um So it asks for the reaction of the rate determining step. So that would be be right. And then lastly, you want to look at overall energies. So your first step wants to know if you're going to be end organic or X organic. So remember the end organic versus X organic, You're talking about till two G. So if something's undergone it, delta G is going to be greater than zero. And if it's extra granic, delta G is going to be less than zero. So if you look at your first step where you're going from A to B, this overall changing energy is positive, so B has a higher energy than A. So B minus A is going to be greater than zero, so you're going to be and organic. However, if you look at your overall reaction, so your first step is from A to B. Your overall reaction is going from A. Just need this down a little bit. Your overall reaction is going from A to D. So because A going from A to D. You go down in energy, so D is lower in energy, your overall delta G is going to be less than zero. So you're going to be extra guards.
