At $400 \mathrm{K}$ the value of $K_{\mathrm{p}}$ for the reaction $$\mathrm{N}_{2}(g)+3 \mathrm{H}_{2}(g) \rightleftharpoons 2 \mathrm{NH}_{3}(g)$$ is $41,$ and $\Delta H=-92.2 \mathrm{kJ} .$ What is the value of $K_{\mathrm{p}}$ at $700 \mathrm{K} ?$
A question in Berlin. 18 Miss trucks, of all our reaction. Now entertain Jess with you guys to give you a moment on your cooking. You keep you value on the career each marrying the think. So, Ellen, 41 over came to because Ellen Okay, one kitchen is equal to negative learning. 0.22 Sure. Yeah. To attend to the fourth goals. So this is your no change over your guess, Const. English see 0.314 times went over 400 counting minus one over 700 Killman. Which gives you Ln 41 over, Key to. And she could to 11 38 when, uh, raise it to the E to cancel that you're Ellen. You 41/2 is equal to eat to the 11.8. Then K two is 41 divided by each of the 11.8. And key to will be equal to true printing terms. 10 tu minus four
To calculate delta G. For the formation of N. 205 from the following reactions. Let's rewrite the following reactions. We've got to H two S reacting with 02 to produce two waters liquid. Then we've got into a five reacting with H 20. Liquid to produce two A channel three liquids and then we've got a half a nitrogen reacting with three halfs and oxygen and half a hydrogen to give us the one hydrogen, one nitrogen and three oxygen's. So we want this reaction here Where into reacts with 5/2 of an oxygen to produce N 205. So that means we need this on the right hand side. So we're going to have to reverse this reaction which will cause us to change that sign. When we reverse this reaction, we're now going to have to H. N. O. Threes on the left hand side. So we want to cancel the H. N. O. Threes on the left hand side with these that are on the right hand side. So we're gonna need to multiply that by two. We multiply it by two, we multiply this by two and then next we need to get rid of our waters. So we're going to have to if this one was reversed, this one is going to have to be reversed. So the waters are on two different sides And then we're gonna have to multiply this by 1/2 in order to just have one water here to cancel with this one water. And when we do that will change the sign on this and multiply it by 1/2 And that should do it. That's going to then give us 5/2 of oxygen and everything else is going to cancel. So delta G then it's just going to be the some of these delta G values or 114.98 killer jewels.
Today I'll be going over questions. Remember 1 11 which against you two equations and your particular your T p A. So you have in 202 The 19. Oh, enough to we're doing on to, you know, 02 and all those over to to A and O us. Oh, to you two and two. So how, you know, jeans for both, You know that to be is continuing to this one's Maybe they're 67 point well, here in 16 69th return. And then these comes out getting to lost two or two, 222 which is the equation that you have at the top. So that means you have to add these two, which is gonna be 103.5. So it will be one or three 500 jewels over 8.314 books 8.314 times 2 98. It gets your negative. 40 will come soon. And then your KP E to a 1941.7, which is gonna be equal to so pretty soon. Times change minus we to
Do you today? I'm going on the question and so on. Whether tells you kept Doctor que Well, use your doctor change. Okay. Okay. Here. KP. So you have and two guys plus O two guys to give you. Then e have to Well, to a no. To you know, many how you're too. And oh, plus go to to get to in order to you have your doctor's. Jeez, which is one so only 3.2 killing jewels O negative. 69 point sarin killer jewels. You can't leave out to get into gas plus two or to gas, you know to They know too. Yes. Then when you do this temptation that well, 3.52 groups then race. So then you do 103. 500 Jules over 8.31 four turns your 2 98 to get used. 7.24 Thanks. 10 to the minus. Right. Teen. Mhm more before your KP You do. 7.24 turns turned to a minus 19 dreams. Holy 082 What? 06 10 3 to 98 running of the rooms. Race this part. Yeah, number one. And this will give you two 0.96 terms. 10 to the minus 20. Mhm
