Use data from Table 10.3 to estimate the enthalpy change $\left(\Delta_{\mathrm{r}} H\right)$ for the following reaction. $\mathrm{C}_{2} \mathrm{H}_{6}(\mathrm{g})+\mathrm{Cl}_{2}(\mathrm{g}) \longrightarrow \mathrm{C}_{2} \mathrm{H}_{5} \mathrm{Cl}(\mathrm{g})+\mathrm{HCl}(\mathrm{g})$
$\Delta_{\mathrm{r}} H=?$

Let's solve the problem from the chapter. Chemical bonding part one. Basic concepts. This problem has given a chemical reaction between the 286 including to give three to H five seal and it's hell for this reaction. We have to calculate the Delta that is not in therapy. Change for the reaction. We will refer table 10.3 from the book to get the values of different born in Tel piece. So first of all, let us represent the reaction in terms of the level structures of different reactant under products just to know the bonds, which are broken and formed during the reaction. So these are the level structure for different reenactments and products involved in the reaction. Looking carefully at these structures, we get to know that the bones brutal, UH, one more of carbon hydrogen and one mole of chlorine chlorine from the table. The energy change involved is 414 kg. You'll for carbon hydrogen bond and 243 kill a jewel for chlorine chlorine bond. The breakage of bone involves absorption of energy, so and there's e required for breaking bones is equal to 414 plus 2 43 kill a jewel. And that comes as 657 kg jewel. No. From here we can see the bones formed, uh, one more of carbon chlorine and one more of higher ozone chlorine. The energy change for formation of these bonds is minus 339. Kill a jewel for carbon chlorine bond and minus 431 kill a jewel 400 including bond. Since the formation of bond involved release of energy so energy released to form bonds is equal to minus 339 plus minus 431 the usual and the total comes out as minus 770 kilo June. Now the net until P change for the reaction can be calculated by adding these two energy values, that is 657 minus 770 kilos rule and the value comes out as minus 113. Kill a June caramel so Delta H for the given reaction is minus 113 kilo. June per mole

All right for this problem. We're finding the change in Antebi and Tropea of HCL in a gash state and as well as hydrogen and chlorine and its cash at stake. But as you could see, this equation is not in violence. So we have to put a 1/2 apple reactivates, and then we're just going to calculate from there we got change of the entropy, which is just going to be negative 92,307. Notice that there is no dust bowl there because this is in kill jewels. All this is just in jewels. So I'm moving a decimal over three places to the right, minus zero. So I was just going to be 92,000 307. Change in entropy. We have we have hydrogen, but then we're gonna divide it by two. Because of the 1/2 over here that is going to be 65 point for three to notice. I'm doing the reactions first because I have to add them. Next. We have Corinne also get to divide that by two to get 1 11 533 and those two, we're going to get 1 76.9 65 and then we're going to subtract 1 86.908 by the number we just got that's going to just be 9.9 and then to see whether it is spontaneous or not, we're gonna use the Gibbs Free Energy equation. And that is just the change in entropy, which is 92,307 minus temperature, which, at standard condition, is always gonna be 25 degree Celsius. Or in Calvin, which is, uh, to 98 times 9.9, which is the change of entropy. And with that we're going to get negative 95,000 257.2. And this is going to be spontaneous because his G it's greater than zero is not spontaneous. But as changing G is greater or less, sentence gives me zero. It is sportiness

This problem, we're gonna be using the standard of a piece of information to calculate the implicated. The only real reaction that we get in here were in use. This equation in which we heard the uncle views of the illusion of the products minus that of reactions equals B and B in the overall reaction. So this reaction we're gonna have more moves. No one more often, Jerry Linus, A few moves steel to plus most of H 20 And that's in a liquid form. Just want to be careful because there is a formation are different for water, whether it's a gas or a liquid. And so now we conclude in the numbers to bees. So for HCL, it's gonna negatives minding too. Going green Born. That's gonna be killer jewels, mo. And then for oxygen. It's going to be zero because it's an element in its natural state. So lengthy temple peer information with zero so same thing for sealed, too. You gotta just gonna use the rules, and that opens Wow and water in the liquid state, we're gonna have Teoh multiplied by negative 251 to get killed. Jules, goal and then one calculate that our final in Syria is going to be to you too. 0.36 you would rules for this overall reaction.

This problem, we're gonna be using standard uncle use of coordination and sympathies of reaction to find the missing and be information in this react. So what we're looking for is the end of the information or common touch for kind of working backwards backwards in this problem, not going to be using the overall and will be of the reaction to solve that it was were already given that in this capes. So the entropy of the reaction is gonna equal chill for fines will be inflammation. H CEO. What's that of C seal? Or when we're not some track ch four and boring and were given that uncle beyond the reaction news. Negative green on you, son. 1.3. No, yours were low. And we can use our table to figure out that of age snail. So it's gonna need I need to do 92 point green one, and then a four carbon touch of border brings going on even X, which is what we're gonna be solving for my mom. For methane, that value is negative. Negative. 74 0.8 Lawn women for Korean since its and it's it's a gas in its natural state is gonna be zero for the end of the information so we can rearrange this equation to solve for X. I'm gonna have that. Thanks. Ukuleles mangling 3 97 13 plus for 92.31 minus 74.81 equals morning. 2.8 someone Miller jewels. Whoa! I'm asking you your final answer as the standard and will be information of carbon touch report.
