 Anyways, let's do this, okay? Too bad I didn't get that already, that was pretty hilarious. I am used to myself sometimes. So, let's try another equilibrium constant, right? So, first thing we're going to have to do is find the equilibrium constant expression. But before we do that, right, we're going to have to balance the equation, okay? So, balanced equation has to occur before you can get the right equilibrium constant expression, okay? So, we look here, pretty straight forward. We've got two hydrogens here, two hydrogens here, and only one of each here, right? So, just put a two there, and it should be balanced, right? Everybody agrees? So, let's do the equilibrium constant now, KDQ. So, again, this is going to be just like the last few problems that we were doing, right? But, this time they gave us numbers to plug in. So, why don't you guys help me out since you guys know how to do this now? What would be on the top? Concentration of H2, right? Hydrogen gas, because it's a gas, right? And iodine is also in the gaseous form, so it's going to be concentration of I2, right? Like I said. And then, on the bottom, what is it going to be? Concentration of H2, I2. Yeah, concentration of H2, I2. And now, we just plug in the numbers. Remember what I said, equilibrium constant does not have units. So, don't even worry about the units, okay? So, if they're already in molarity, then you just throw them in. So, we say 0.54, 1.72, I mean, 1.72. It's easier to see on a piece of paper than this one. Provided by 0.54, like that. So, that's going to be equal to get out of your calculator. 1.72. 1.72, and 1.72, divided by 0.54. So, what did you guys get? So, it's going to be 10 points, okay? Because of this, but notice, it looks weird. Why? No units, huh? It's like, very strange in chemistry to have something without units, okay? So, is that cool? Does that answer your question of how to plug it in? Okay, cool. So, are there any more questions about this one? The interesting thing about this KEQ, does anybody know? Does anybody recall from reading the chapter? Ha ha, right? What it means to have an equilibrium constant that's above 1? Does anybody remember? Okay. So, just so I won't torture you guys on video. If you have an equilibrium constant above 1, that means the reaction is favored to the product sum, okay? So, we've got something that looks like that, okay? So, if the equilibrium constant was less than 1, so it's always going to be above 0, okay? So, you have to decide whether it's below 1 or above 1. If it's below 1, it means that the reactions are favored, or this is not a very good reaction, okay? If it's above 1, then it means that the products are favored, and that's a good reaction, right? Because you want to produce your products, right? That's what you do in your reaction course. Is everybody cool with that? Okay, so recall that when I asked you about above or below 1 when KEQ, okay? Any questions? Okay.
