Identify which of the following is true for the reaction N₂(g) + 3 H₂(g) → 2 NH₃(g)

Accepted Answer

Hey there. Alright, so here we need to predict whether the following reactions will be eggs are thermic or endo thermic. So first let's go ahead and talk about what our eggs, Oh and what are endo thermic reactions? So, eggs ah thermic reactions or processes are going to be bond forming processes bond forming the spin just doesn't want to work. And in terms of gas phases or I'm sorry, um phases of matter, we can say that is going from gas to a liquid to a solid. So all of these processes are bond forming, right? For endo thermic, it's just the opposite. It's actually bond breaking process, bond breaking. And then for the face changes is going to be going from a solid to a gas or solid to liquid to gas where we're breaking the bonds in order to do that. All right, so now that we know that now that we've recalled it, Let's go ahead and take a look here. Alright, so for the first one we have um everything is in gaseous face, so we can't use that. But we can see that we have, you know, to separate molecules, right? One of and 21 and three of H two. Um So actually, you know, in total we have for here and then we combine it into one of you know, the same molecule, but just two of them. So we're basically um forming bonds in order to combine these two molecules together. Right? So this is going to be exact thermic and so, okay, for the next one we have sulfur and oxygen. Gas and then we produced just one product again. So just like before we had two different compounds and we made it into one basically. Right? And again, everything is in gashes states. So we can't really use that. But we can see that we've formed bonds in order to combine these two into one compound. So again, this is exact thermic. Okay, so we have exiled, exiled. And then the next one we have here, we're actually having some face changes. Okay, So we went from a solid and we still have some solid but we've actually um made some gas. So we went from a solid to a gas. So this is definitely going to be an endo thermic process because not only did we just take, you know, one compound, one molecule, and we split it into two. So we we broke some bonds and we also have changed the phases from a solid to a gas. So this is endo thermic. Okay, next we have water. So we're starting with one compound and we're actually producing too. Okay, again, gas, everything is in gas phase. So we can't use that. But we can see that this is going to be um endo thermic because we took one compound, we broke the bonds in order to make two different compounds. So this is endo thermic again, because we're breaking the bonds here. Okay, and then finally the last one again, gas gas, so we can't use that. But we can see that we have one flooring here. Well, we had to separate florins, right? And then we've taken those two florins and we made a bond between them. So now that there's there's only one molecule contains both of the florentines. So we've actually formed some bonds, Right? So this is going to be exact thermic yo sorry, I'm having problems. Okay, So we have eggs, eggs. Oh, endo, endo and exo as our answers. Thanks so much for watching. And let us know if you have any questions.
