 Okay, so let's do this one, is the Haver process for the industrial synthesis of ammonia, spontaneous or non-spontaneous, under standard conditions at 25 degrees Celsius. So they give us the temperature, 25 degrees Celsius. But we need to put that into kelp because remember our equation is delta G equals delta H minus T delta S, right? And they give us delta H, negative 92.2 kilojoules. And they give us delta S is negative 199 joules per one kelp, or joules per kelp. So they give it to us like this, I guess I should write that as joules per kelp. Okay, so two things you've got to do. Notice this is joules, right? Not kilojoules, okay? And this one is kelp and dot degrees Celsius, okay? So how do we get from Celsius to kelp in 273? So what is this? 298, okay? So what are we looking for? Oh, here, let's write down the reaction equation too. So it's N2 gas plus 3H2 gas goes to 2NH3 gas. You didn't need that reaction equation to do this problem, but since they gave it to you, we're not so very careful. So we're looking for delta G. Delta H is already N kilojoules, the 92.2 kilojoules minus T is now in kelp. 298 kelp is 199 joules per one kelp. And in order to add the energies together, we've got to convert either this one to joules or this one to kilojoules or this one to kilojoules. So hopefully you can already see much smaller the entropy is usually much smaller than the enthalpy. So cancel, cancel, cancel, cancel. So I guess we're actually looking, we're actually finding because we've got standard states here. So let's do it. 298 times negative 1, 99. B, 6, 6, better one after the decimal place. Well, the other one doesn't have one. So we'll just do it to 2, 6, 6. Negative 33. Since they're all gases, what's actually happening? What do you mean? Reaction like that. Like is it like a gas? Quite another gas, maybe another gas. Mm-hmm, yeah. So what if you want to think about the, you know, like we've got nitrogen and colliding together. But of course it's going to take three of these. They don't all necessarily have to hit each other at the same time. And they're going to be making two little homologous. We'll talk more about that in organic chemistry. We'll talk about, you know, reaction mechanisms and stuff like that. Okay, are there any other questions on this one? Okay, good.
