This video should be mandatory viewing for all high school chemistry courses. It's a reminder that chemistry is truly applied physics.

This is probably the best theoratical chemistry channel right now

One conceptual mistake I run into frequently is the idea that materials at a particular temperature have all their particles at the same kinetic energy, and thus chemical reactions (including side reactions) turn on or off as you raise or lower the temperature. In reality, at a particular temperature, the kinetic energy of the particles is distributed along a curve with most of them in middle range and smaller and smaller amounts as the energy gets higher or lower. So at any temperature, there will (theoretically) always be *some* with enough energy to reach the threshold needed for a reaction to occur, and controlling the temperature just raises or lowers the fraction of particles that do so.

@MadScientist267

Correct. The "temperature" is the *average* kinetic energy. Some will have almost none, some will be flying. Most will be about down the middle between the two, and that's the reading we get.

@@crackedemerald4930 yes, also why liquids “mist” from falling or splashing. as long as at least one particle has enough energy to overcome internal tension (like surface tension for water, specifically), it is free to escape and fly off. it happens all the time, and there is actually a calculable integer to figure out when it usually tapers off, known as “vapor pressure”. it’s why you don’t see much evaporation in a room temperature water bottle as opposed to a puddle. i mean, there are other nuances that depict the specific scenarios, but generally, if theres less room for the water to evaporate into the air, less water evaporates. pretty cool!

Good, isn't it?

Nice work! I'd like to suggest more intro about molecular chemistry ( orbitals, etc) in reactions. Examples: H2 +O2 goes with explosion with practically any concentrations, any temperature, etc vs rusting going relatively slow and really depends on reaction conditions. Pb(N3)2 is very sensitive, very often self exploded under any conditions vs reactions require some concentration, temperature etc. One more suggestion is to talk about how chemical properties define the speed of reaction. Examples: H2+O2 -> blast always, but oil+O2 -> slow combustion always. Bonus topic, IMHO, about 'unknown' reactions. Example: plastit usually is very safe explosion. To detonate one, the one needs to apply high voltage like 15kV. For this reason, plastit is used for R&D work with explosions. But sometime plastit can detonate from unknown reason. It is very seldom. In my personal work, 2 times for several years. I had collected unused plastit into a wood box and blast happened. No reason, very seldom case, but could happen.

Activation energy out tomorrow!

My first instinct would be that, by saying “molecules are floating around and the right bits need to hit for a reaction to happen”, we are excluding the combined effect of this extremely intricate, quasi discontinuous 3D texture of forces acting between EACH of these huge number molecules. The complicated movement the magnetic forces start to cause in small distances are also disregarded in all the 3D modelling we see in this video, e.g., at (1:38). I was really missing that, even if it’s something one might have hard time to model correctly. It wasn’t even attempted even if we know that the devil is in the details:) I’m sure that “the appropriate angle” is a wide range of angles in which the probability of reaction forms a curve. Is it meaningful and even possible to formulate an experiment to actually draw that curve with considerable precision? Worst of all, this curve is actually a surface, because an additional dimension, the energy (and frequency) of the collisions comes into the picture, not to even mentioning the potential other factors affecting the chance (and even the potential structure) of reactions that are happening. I’m also wondering what is supposed to make the distribution of the covalence electrons residing at the outside of molecules creating those crucial “patches of charge” that creates the slight attraction, which is pictured as a random fluctuation in local outer charge can possibly create a combined effect of general attraction as we hear at (3:25), and whether that fluctuation can or cannot be described as a wave, with frequency and even possibly amplitude. This is the first time I actually realise that the behaviour of nuclei are perfectly linear (they are evenly repelling the other nuclei while a reaction happens) while the electrons have that constant “fluctuation” of charge in themselves, which is crucial for the interaction with another entity to happen forming molecules and, later, complex molecules. Electrons, unlike protons and neutrons, are supposed to be fundamental particles. The question might automatically come: how can something so fundamental have such a complex behaviour like developing patches of different charge?

@ThreeTwentysix

2 ай бұрын

There are many parts to this question and I'm going to keep this brief, so this is just a starter: You”re absolutely right that reactions are, in general, much more complicated than I showed here, but: 1) This is why I chose an inherently simple system. You are right that there is a correct cone of approach, but we can simplify that to a simple line without losing much information. However, detailed calculations would take that into account. 2) There are actually many ways reactants can recombine to make the products but we focus on the lowest energy path because energy appears as an exponential in the equation for determining how fast the reaction goes. In short, that means that the difference between the lowest energy path and the second lowest energy path makes a huge difference to the reaction rate, and the second lowest energy path is *usually* insignificant. 3) The fluctuation of electron density is known as Van de Waals interactions. Electrons in molecules can do this because they ‘move’ much faster than the protons. Similar situations do occur on the atomic and molecular scale, however, with temporary patches of relative positive and negative charge causing static electricity and lightning, for example. I did a video on static and another about lightning so check them out if you’re interested!

​@@ThreeTwentysix Thank you for caring for random viewers! 3) I will, most definitely, watch your video on static electricity, and will have a better look at the works of Van de Waals. 2) I wonder if we could just handle the steps of chemistry (disregarding particle physics for now... forming of compounds and molecules, forming of amino acids, combinations of monomers into polymers, proteins folding themselves into molecular machines... disregarding biology for now) as black boxes, and then ask ourselves in which particular box does emergence happen and guided by what factors? Can we “blame” those virtually random fluctuations, and usually insignificant events, that are equally happening in each above organisation level, for this emergence to apparently exist?

Just found your channel. I asked a question under a different video and I apologize if I've missed that and asked a repeat... Why do most chemistry videos show a beaker full of liquid, and a spinning magnet stirring the liquid, and then a series of "precipitate this, precipitate that" steps, and finally some interesting powder... I'm expecting the kind of reactions that happen in ATP-synthase. You know: the motor that sits in the skin of mitochondria adding one phosphate at a time, as the motor goes round... (I'm trying to describe part of the Calvin cycle, in case that's not clear. ;-) Why can we apparently only DRAW pictures of biochemistry, while being unable to actually DO biochemistry...? I did notice that a recent Nobel went for Attosecond lasers, so now we can almost see what happens. Are we still so far away from mimicking mitochondria? I would have thought that every engineer in there place would be building little 3-part machines to build molecules. 👀🤷‍♂️

Could information really emerge from a predictable system that have never received information from anywhere outside of itself? Isn’t it against common logic, science aside? Is “emergence” a procedure that can be scientifically defined, because it has a finite number of factors that keep it working, or is emergence the collective name of all things in our discoverable universe that we cannot explain scientifically - therefore we named it, and by naming it we have created our sacred father AKA emergence:) That’s not science then, that’s a religion now which I have never had and I turned towards science in order to avoid bowing at the smelly feet of an imaginary magician, and what do I find in science?
