For which of the following reactions would you expect the extent of the forward reaction to increase with increasing temperatures? Explain. (a) $\quad \mathrm{NO}(\mathrm{g}) \rightleftharpoons \frac{1}{2} \mathrm{N}_{2}(\mathrm{g})+\frac{1}{2} \mathrm{O}_{2}(\mathrm{g}) \quad \Delta H^{\circ}=-90.2 \mathrm{kJ}$ (b) $\quad \mathrm{SO}_{3}(\mathrm{g}) \rightleftharpoons \mathrm{SO}_{2}(\mathrm{g})+\frac{1}{2} \mathrm{O}_{2}(\mathrm{g}) \quad \Delta H^{\circ}=+98.9 \mathrm{kJ}$ (c) $\mathrm{N}_{2} \mathrm{H}_{4}(\mathrm{g}) \rightleftharpoons \mathrm{N}_{2}(\mathrm{g})+2 \mathrm{H}_{2}(\mathrm{g}) \quad \Delta H^{\circ}=-95.4 \mathrm{kJ}$ (d) $\mathrm{COCl}_{2}(\mathrm{g}) \rightleftharpoons \mathrm{CO}(\mathrm{g})+\mathrm{Cl}_{2}(\mathrm{g}) \quad \Delta H^{\circ}=+108.3 \mathrm{kJ}$

Equally medium constant. Uh huh. Mhm. Constant cake can eat to registration? Yes. Then all Children. Yeah. Yeah. Less than or could you drop them with the equilibrium constant especially is a mathematical relationship relationship. Mhm. That shows how the concentration all project. Yeah. Since educational projects really with a concentration of your chance. Really good concentration of we have dreams. If the value of peace greater than well, you could drink in The one The project in direction. Our favorite without. Put it up to the project in the reaction. Yeah. Yeah. Are favored. Come on. It's a very risky. Is a good one equal to one and then. Okay. No, I did media actors, you know. Yeah. Projects. Our favorite

Let's predict what would happen to the equilibrium upon each of the following disturbances. For a the concentrate CEO Seo too is added, which would increase the concentration of Seo Seal too. And this would cause a shift towards the left for be seal to was added before. That means that seal issue, with the concentration of seal to is going to increase in. That would yield a shift towards the rates and for C seal seal to is removed. That would mean that the concentration of CEO Seo too has been decreased and that would cause a shift towards the right.

There is a relation between Delta s Delta, H and K. It can be the presented US build. It minus d Delta is equals negative value off. Artie, not your look. Okay. We have provided with the reaction off to move off. Magnesium plus oxygen gives me magnesium oxide for this reaction. The signs off both the term Delta s So Delta s on dhe builder h on Negative for both the terms. No. We need to predict the magnitude k equilibrium constant become smaller as delta s becomes negative. This indicates that the magnitude off K is directly proportional or directly influenced by dependency off a system moving towards a minimum disorder. Also, the value off K increases us value off Delta H decreases. Considering the second part, we have to ki i Why should reaction to put ASHA bless ironing in this reaction the entropy That means Delta s will increase that the s will have a positive value. Potassium iodide decompress is to give potassium and iady. This is an end atomic Indo Tor Mick Reaction. The value off Delta h will also be positive. Both the values in this case are positive towards the other. We have sodium too. Giving out two sodium the number off moves off gases. Our increased on the products I that mean and drop e increases. Delta is increase is having a positive value. This is an end atomic reaction. That means the value off Delta which will be positive moving toward the next reaction. We have to be two or five form plus five excision. The number off go moles off gashes, product increase. So that means value often. Elder ISS on DDE value of Delta h Boubacar What's it do? So the part be off the ocean in general discussion. The first reaction is explosive reaction. So the first reaction is explosive reaction. That means it is spontaneous. This means the reaction fevers towards the product side. The value off key will be greater than zero. The rest of the three reactions are decomposition reaction. So the actual number second reaction number third reaction about food, our decomposition reaction That means value off Kay will be lesser than zero

We have to ration. So we have a cesium forthis we've mercury, and then we have adjoining mine. And then I was a hydraulic science. So we have Russian one. So we asked him to. So which reaction we all kind of fasters way? And also which one with the lower activation energy. Okay, so by looking at the we're sure we can conclude that should be the 2nd 1 and I'm going to explain that. So first off, Owen, we have reaction by the collision theory. We must have to, um, Mark you or reaction or particle to coli be shattered. A canteen contact the shoulder. Okay. So when they ah, right, we have two more Q approaching with your shoulder. So we have to bowl for here, are pushing to reach order. So at first they were experience of repulsion force because off their have few naturals, they will have a natural clough just surrounding them. You know, you just add some death, what they have in the atom. So when they approach each other, they were experienced that of repulsion force. So when the repulsion forces higher the market, we need more kinetic energy to overcome that repulsion for some more candy. Angie. And due to this with repulsion force, um, this repulsion for can be consider as to activation energy. But also, activation in energy also depend on other factor as well. But normally we have two more cubicle, I think in shoulder to repulsion for me because of that, the activation energy. Okay, when we go back to our question to our reaction equation, you can see that the first week we actually we have to Ah, Brian also seem for the second we asked you. But the first reaction we have two positive I and one of every four poster charge another one were to lead to put two balls in charge. So for this case, they are highly positive. So we are not going to look at ah natural over over here. But already I am. So stay over. Um, they're positive for the charge over people. There are over a part of charge. Okay, so every know that we have the same chartering repair the shoulder so very experienced. Ah, chart repulsion duty to poison charge on the aren't and you can see they want therefore, when it's too. So the massive Charles pretty high. And also they are hardy. Ah, poison charge. So when this too. I'm a poor church order. They explain a high. Um, we're really large repulsion force. So that's what they will even hire Qin that the edge there are pushing each other to ah could have each other to initiate a reaction to initiate the reaction. So therefore they have high repulsion, so they will have a higher at originality. Hi. It's efficient energy. But you know the world when we actually looking at ah, um ah, second reaction were high. Julian Julian. And also we have ah hydroxide time. Hi, Julie. Um is for the charge Hydro sites there charge, as you know, that positive charge. No charge couples in charge. They have attractive force. So you still off the charts? We power in the charter because they have opposing charge. Essentially, they're attracting each other in additional to their original. They have a gigantic energy. They will for certain velocity. When they are poached each other, the attractive force even bring them closer to each other. So in other words, they don't get a lot of chaotic. Angie to a pain bring to Ryan together. So the the situation energy will be decreased. So were the lower Activision Energy. The weight we also be be faster. So that's why the second reaction we have the fastest.
