Consider the following hypothetical reactions: $$ \begin{array}{ll} \mathrm{A} \rightarrow \mathrm{B} & \Delta H=+30 \mathrm{~kJ} \\ \mathrm{~B} \longrightarrow \mathrm{C} & \Delta H=+60 \mathrm{~kJ} \end{array} $$ (a) Use Hess's law to calculate the enthalpy change for the reaction $\mathrm{A}-\cdots \mathrm{C}$ (b) Construct an enthalpy diagram for substances $\mathrm{A}, \mathrm{B}$, and $\mathrm{C}$, and show how Hess's law applies.

So if we want the reaction from A. To see if we simply add these up, then the bees will cancel out like an algebra and then has his losses that we can also add the heats delta H one plus delta H. Two which is 60 minus 90 or 30 negative killer jewels for the reaction. And that completes friday for part B. Let's superimpose the entropy diagrams and show how has this law applies here. So if you have the delta H. Um as the reaction progresses, reaction coordinate or time or whatever you want to call it for A to B, let's do it in red. We start with A go up and we'll get B. And this is going to be 60 kill a jules. And then if we go from B to C, We go down negative 90 killer jewels. So this right here, it's not really to scale but you know in that seat. So then if you compare A. And C. It's gonna be um 99 and 60 is this is going to be 30 killer jewels. And since he is below a, it's going to be a negative number. And that shows why because they're all path, the overall process is our path independent to calculate the entropy, you can just um mathematically add the values according to Hess's law.

In this question, we're giving the following energy graph for the reaction to CH. Three goes to C. two h. 6 first. We want to find out what the activation energy of this reaction is. So from this graph, you know that the activation energy is the amount of energy in between the reactant A. And the activated complex C. So that would be eight kg joules. So the activation energy Is equal to eight. Kill angels. Next we want to find out The point at which to stage three would appear. So since two stage three or 4 reactant that would be at point a. Okay. Next. We want to find out the Delta H. of the whole overall reaction which should be the difference in energy between your products be and to react in a. So it would be negative 360 killer jewels. For the next part we want to find out what the activation energy of the reverse reaction would be. So the activation energy of the reverse reaction is from is the amount of energy from your products to activated complex. So that's 360 plus eight So 368 killer jewels. Next, we want to find out the point at which since you age six would be definitely found, which would be when all of our reactions have been converted into products at Point B. Finally, we want to find out what the species at Point C. Is called, which is generally called the activated complex.

All right, guys, for question number 62 in Chapter five of Chemistry Central Science. We're going to be using Hess's law to figure out that's how to calculate the change in entropy from converting product A and product. See, So has his law can be summed up basically like this? Yeah, Delta age of reaction equal to Delta H of products minus delta about the age of reactions acting. So basically it doesn't matter. They're what direction you go from. From point A to point point c so long as you're going from point A to a to point C because that change in that change in energy, regardless of how you're getting there, is always going to be the same. So we're so we're going from A to B and then b two c. So the way to figure this out is to to add our equations together, which is going to us, which we're going to have an left side. The bees cancel out and then we'll be producing C. And then the Delta H is going to be Delta H is going to be. Some of the adults ages 30 plus 60 is equal to 90 killer jewels. So now we're going to look at an entropy diagram to better understand how this works. So Oh, a So we're dealing with an epidemic of rational. So we're gonna be going from a low energy level to a high energy level level and over the course of the reaction so you can see how the energy levels change over the course of action going from from a and we can convert to be and where it's going to be. A net increase of 30 killer jewels, jewels in the energy state. Wouldn't doing this aid to be transition. We're going from B to C. You can. We're going further. Increase H and H by 60 killer jewels. Now, remember what I said. It doesn't matter what direction you go from A to bus from a to reach the sea. It just matters that you're going from a to seize. That is always going to be constant. That's it. So it is going to be the sum of 30 killer jewels and 60 killer jewels, which is 90 killer jewels. Mhm. So that's that's very important to remember the regardless of what? What what pathway you're taking so long as you're converting a to see the change entity will always be the same no matter what

Consider. Mhm. The hypothetical reaction. Mhm Yeah because a reacts with me to give cnd with delta equals two minus 1 25 kg jule. Mhm. Given activists and energy yeah of forward reaction. Mhm denoted by E. F. Is equal to 37 kilo june, activists. And energy of reverse the accent is denoted by E. Uh We know that in therapy of reaction dale diet is equal to activists. Energy of forward reaction minus activist energy of reverse reaction. Mhm. So we get activists. Energy of reverse reaction is equal to activists near the forward reaction minus in Turkey. A reaction here. Activist energy of former days since 37 kg jule And tell that equals 2 -1 25. spiritual we get E. R. equals two 1 62. Hello julie. Now we have to draw energy diagram for this reaction. Mhm. Mhm. Okay. Mhm. Mhm. He had X axis indicate the Jackson coordinate. Wait and Vieques is indicated get infected potential. Energy they're delta is negative. Therefore potential. Energy of reactant is higher than potential and as your product. Yeah this is C plus d suppose this line indicates energy barrier for this reaction. Okay. Mhm. Yeah. Okay. This curve indicates progress of reaction. The Yeah, this point indicate for missin off activated complex. Oh God. Mhm. This energy gap indicates activism. Energy for forward reaction which is equal to 37 kg jewels. Okay, this energy cap indicates activists and energy For diversity action which is equal to 162 kilo jule. And this energy gap indicators in therapy of the accent Which is equal to -125 kilo june. This is a reaction energy diagram 40 given hypothetical the action.
