 Okay, so let's start off the day with this question. It says The value for Kc for the reaction to nitrogen dioxide goes to Dynitrogen tetroxide is 1.52 at 319 kelp What is the tent? What is the value of kp at this temperature for this reaction? So This is the reaction here. That's given to us It gives us the Kc and the temperature of the reaction and it wants us to find the kp Okay, so the first thing you want to do or the best thing is that you remember the kp to kc Equation if not, you're gonna have a hard time doing this problem So kp to kc, right? You have to multiply it by RT times delta in So What are these things? Well, we've got T And we've got Kc remember R is Just going to be the R of the gas constant 0.0821 liter ATM per mole Kelvin Okay, but delta in we get that from the reaction equation up here Okay, so delta in It's going to be so that's the change in the number of moles So just like any change it's going to be the final minus two pardon me the initial so The number of moles final well the total number of moles on this side of the reaction equation is just one Of gas So we're looking for moles of gas how many moles of gas we have on this side two right so two moles of gas so what we're going to say is one mole minus Two moles of gas and that's going to equal negative one moles We're not going to use that unit in this, but it's good to know what we're looking at Okay, so are we cool with this one? Okay, so I'm just going to put Delta in equals negative Okay, so now we've got everything so it's just really a plug-and-tie problem now so Kc 1.5 0.0 821 liter ATM per mole Kelvin 319 And that's all negative one Okay, so Go point zero eight two one multiply that by 319 Raise that to the negative one then multiply that by 1.5 two And you should get an answer Zero point zero five eight zero Okay, so no units that you're keeping any questions on that one
