All right. So for this one, we're trying to find an equilibrium Constant K Ah, at 6 55 Kelvin for some reactions that we looked at earlier in problem 74. And so we'll start with the first reaction which is to And there, too going Tonto for And so the first thing I would do is I think back to how do we calculate the equilibrium, Constant K? And so you look at this formula Delta G. He goes, Don't the Jeannot plus r t ln okay, and so we can calculate Delta Do not. And we can't estimate Delta G if we know that the age not indulge us night and our is a constant and then t is 6 55 So from there, once we found Delta G, not in Delta G, we can get what K is by solving the algebra, and so that's what we'll do. So find a G night. You do Delta G A formation of the products might have still to g information of the reactant ce accounting for the molar ratios so you can find these values in your textbook. I'm just gonna write them down 99 eight minus two comes 51.3, and that equals minus 2.8. Killer Jules. So it's fine. Delta H not. He's the same process of non 0.16 Minus two terms. 33 queen too, equals minus 57.24 killed Jules. And we'll do. That s up here. Oh, quick. Don't. That s not equals Korea. Four 0.4 minus two times to 40.1. And that comes out to be, um, if you convert to kill a Jules, it's minus 0.175 A kill Jules per coven of values so we can plug in and find out estimate what Delta G is. So don't thingy is approximately still the age nine minus 6 55 which is the temperature comes that the s not. And so, if you plug those values in, you'll get approximately 57.9. And so from here we can solve the equation. The fine, the equilibrium constant K 77.9. Finessing killer Jules, he cools. Might is two point eight, plus, the constant are which in killer Joe lt's point 008 314 killed. Jules promote Kevin terms 6 55 times the natural log. Okay? And so we could just solve for this. And so me enough getting 60.7 equals 5.45 natural log. Okay? And so if you raise both powers to e k equals 66171.2. So that's reporting. RV was held the same way. Ah, little tricky part in the middle. So this is a grooming gas going to chlorine gas with chlorine gas going to through the e r c e o. It's a gas. So they give you Delta G, not a formation. Ah, just be our CEO. So if you multiply that by to account for the moles, you get minus two curdles, don't age not is also given for permission from B r c e o in delta h for B R. Two unsealed to above zero. So it's just two times that constant they give you, which is 14.6. And so you get 29.2. Killer Jules, don't as they didn't give you. But you can solve for it using the Gibbs equation. And since this is it standard temperature, you can do to 98 comes off the s not. And so you just plug in these values and you can sell for Delta s on Delta Ass night. Turns out to be and kill Jules 0.1, uh, killed Jules per Kelvin. And so again, you can take all these numbers in approximate what? Delta G at 6 55 Calvin is 29.2, minus 60 of times, dear. And so you get approximately minus 39.6 killer Jules and then completing this offer to equilibrium Constant K. So minus 39.6 equals minus two plus zero point. Uh uh, 831834 co jewels for Calvin terms 6 50 Mentor log. Okay. And so then you have you solved through the algebra you get minus 6.95 equals natural log of K. Raise both sides to e in K equals 0.1 And that's how you do this problem.
