t's a poor word choice IMHO but we're stuck with it seems; it's definitely a source of confusion for students. When we say "spontaneous" in general usage we typically don't mean "self sustaining once activated'!

Your channel is a great 2nd-3rd level dive into the physical sciences. I've been watching a ton of physics stuff on youtube, to the point that they are becoming repetitive (Ii'm still extremely thankful for them!). Then I found your channel and I feel like I'm leveling up from all the other great material scientists have contributed. Thank you!

22:46 That example of weathering of surface due to friction💀

Very good intro! I'd add more math to show Arrhenius law equation. I'm kind of a math person to go forward from an equation for: 1. Any complex multistage chem reaction could be easily described as a superposition of several reactions each of them has Arrhenius's nature and a cumulative Arrhenius equation can describe a multistage reaction ; 2. if a chem reaction has several physical stages, like liquid kerosene combustion, when kerosene is vaporizing first and chem reaction going on in gas phase only, such complex transition could be described by cumulative Arrhenius equation as well! Chemistry is easy with math!

That is an excellent point and it's actually what happens with the rate equations (which is where we're headed with this series). That said, it's the activation energy of the rate determining step that makes the biggest difference since AE is an exponential term in the Arrhenius equation. But we'll talk about that in Transition States v. Intermediates, coming up.

Listen Doc, Thanks for these videos. Here's to you for doing this stuff, and being honest and clear about it.

Love love love your presentations. Thank you. More topics? Anything that interests you.

I'm really grateful for your videos! Thanks for delving a bit deeper while still explaining topics so clearly. We'd love to see a video about reversible reactions.

I'll be so glad if you made a video about volatility or about topics like fluorescence, phosporoscence, non-binding interactionst

Love all your videos. Very educational and all presented.

This was really well explained, especially with the animations. Thanks

Love your videos, like they’re always well put together bro

Thanks! You could also make a video about self-ionization (autoionozation) and homoassociation - I am struggling with understanding this and there is little information on encyclopedia. For example, the salt called sodium diacetate (the "salt & vinegar" flavor from Pringles) is a solid of two molecules of acetic acid and one (!) molecule of sodium. The "complex" is neutral because the two acid molecules share hydrogen atom. But how is that possible? I don't understand the dotted line - how can hydrogen be stuck between two molecules of acid like that? Another typical example is hydrogen fluoride and I think iodine does that, too (the triiodide ion). I think this topic can make your video interesting as you can show how the fluoroantimonic acid (the superacid) works, as it's one such "complex" - the dihydrogen fluoride cation and hexafluoroantimonate anion - it's not just hydrogen bonded to weak nucleophile as in normal acid, but this weird fluoride cation. Thanks for your videos, these are very informative and helful for self-learners like me - especially for revisiting the fundamentals.

Absolutely love your videos

That would be a better topic for thermodynamics, where we look only at the beginning and the end. As for 'quantitatively' I would think that is unlikely to be an efficient process.

Great video. I recently saw a poscast between kate the chemist and neil degresse tyson, and according to your explanation they misexplained hydrohelic acid presuming it's simply a nuclear reaction and does not involve orbitals because they are empty. Which makes me think too, how does a proton occupy an empty electronic orbital?

@ThreeTwentysix

18 күн бұрын

Ooh, very interesting, I'll have to track that one down. But very simply, chemists work with the concept of empty orbitals all the time, whereas physicists appear to treat orbitals as fundamentally being an aspect of the electron, so I'm not surprised that Neil deGrasse Tyson has a different point of view. From a chemistry point of view, however, the only peculiar thing here is that it's helium that's acting as a base.

Hmmm how does activation energy work in terms of transition state and molecular potential energy for something like nitroglycerin? Is there no transition state/the electron orbitals are "stretched" enough already so an explosive reaction can occur through simple contact?

when a substrate binds to a protein, the whole thing can undergo a conformation shift pushing molecules together in the orientation that is favorable for a reaction. the amino acids that make up the protein will also have certain side chains exposed in the active site, that influence the chemical and charge environment right where it needs to be!🤯

Is it actually possible for a reaction to stop completely? Or does it just react verry verry slowly? Because by pure chance there will always be a few molecules reacting, even on low temperature, right?

That's true. Generally, when people say something 'doesn't happen' we mean it's insignificant. But there are times when extreme purity is required where those processes become significant.

I love your thinking style (very few have that) but then you use some extra vocabulary like 'casual knocks', 'external knocks' and some more ... that I and many readers would not know ... so it becomes a bit of struggle to understand.

Three minutes in AND a question: how is 'Activation Energy' related to entropy? your examples were all entropic cliffs..

@ThreeTwentysix

19 күн бұрын

In terms of the overall reaction, it's not related because the entropy of a reaction only depends on where you started and where you finished, not how you got there. But there is an 'activation entropy' which is a measure of how the entropy within the molecules changes to form the transition state.

@Archiekunst

19 күн бұрын

I'd say the entropy is hidden in the difference between the initial and final states. That difference is actually the free energy of the reaction which is also expressed as enthalpy (heat of the reaction) - temperature × entropy. This is thermodynamics and tells if and how much something will happen but tells nothing of how long it will take. The activation energy is different and is kinetics, as in how fast something will happen.

0:58

Choleric people also have a low activation energy 😉

This may solve the mystery of why the buttered side of the bread lands face down if dropped 😲

The past is full of smoothed surfaces 😅

It has always bothered me when I read explanations like 'an exothermic reaction releases heat'. Your explanations are filling in the gaps. It's the increased kinetic energy of the reactants, either directly by being attracted and exchanging potential for kinetic energy or indirectly by subsequently transferring this kinetic energy to other electrons/atoms/molecules by crashing into them.
