This experiment is for reaction rates. We are using special chemicals to show how slowly, what you drop it, the slow reaction happens. And if you throw it down, the faster reaction has to cool. Oh, numero uno! No! Slow reaction, I'm going to drop this and it will just phase like sons of guns. Okay, now come look. Pizzing like sons of guns. Numero dose! Time for reaction. Put it on as tight as you can. Then you're going to shake, shake, shake, shake, shake your santa, shake your santa. This is a paid sponsor. The dietary compound of santa and chemical. Shake, shake, shake, shake, shake, shake, shake, shake, shake, shake, shake. No! You actually have to have been little too early. Okay, well, that's reaction. Oh my gosh! Explosion! Wait, this is our example of reaction mechanisms. Step one, contact. Yeah, that's right. Step two, proper alignment. They're very aligned. This is going to be a good fight. Step three, high enough energy to make the reaction happen. See the energy in there? All right, now I will be in the activated complex. Stop! No, sit down. Tadix. Can I add molecular theory? There are four postulates to this theory. Here are my molecules. These molecules are all extremely small and mass. Look at how small we are. Second postulate is that they're all constantly in motion. They never stop moving. They just keep moving and moving. Never stopping. Third postulate. Collegions are perfectly elastic, meaning. When they make a collision and they bump into each other, they go back into their original form and they keep moving. They still never stop. Okay, fourth postulate. Temperature is directly related to the energy. So when I turn the temperature up, they move faster. Let's go turn it up. Turning it up! There we go! See how they're moving faster? Because temperature is directly related to the energy. Higher energy, because I turn the higher temperature. Now let's turn it back so they can give them a break. Turning it down! Alright. Yes, see how much slower they are now? And that is our example of kinetic molecular theory. Okay, this is phase and phase changes. We are showing how triple point occurs. When solid liquid and vapor all happen at the same time. Price, we need a phase change. Oh my gosh, you guys, you're supposed to turn it. And turn! Solid liquid, liquid and vapor. This is the Gibbs phase rule. When I apply pressure, it becomes a more dense phase. But when I add heat, it goes to LS dense phase. See? Wow, that is a definite example of what too much spare time can end up like. Kids, take my advice. Drink your milk. Eat your vegetables. Listen to your parents. And you might not end up like us. Till next time.
