I got lost when you said that the catalytic converter helps cars go fast. The CC will decrease a cars performance due to air flow restriction, which is why there are popular to replace (although it's typically illegal). Maybe I misunderstood something. Also, it's hard to visualize the difference between -8.22x10^-22 and 1.17x10^-21 calories. It would be cool if you could do a comparison, or express that difference in a percentage so more viewers could relate.
No, you're right, he is dead wrong on that part ... the cat is a much hated part of a car as far as performance is concerned. But it helps with emissions which is a much more important issue than 0-100 times for most road cars :P
Yes, you are right, the catalytic converter does not help the car to go any faster. I was trying to simplify the benefit of having the converter when I said that, but I misspoke and just continued speaking. I can't believe I made that mistake! I will be fixing that in a future video. Also, I think you are right about the numbers in scientific notation, and I will try to think of a better way to communicate that in future videos.
Nice animations! It might be worth adding annotation... catalytic converters don't help with speed. However they do keep the freeway from smelling like a gas station. Keep up the good work!
Thanks so much! You are right, the platinum converter does not help the car to go fast. I got ahead of myself when I was speaking and was trying to describe the benefit of having the platinum. It was sort of a quick, informal video that I did a little bit before I had to go get ready for street mining with Cody, and so I wasn't really paying attention to what I was saying. A lot of people have pointed out that mistake, and so I will be fixing that in a future video.
AFAIK The auto engine 'saves' about 2% of the gasoline in order to power the catalytic converter to make it hot. IOW We waste 2% of the fuel that we put into our cars.Reduction of nitrogen oxides to nitrogen and oxygen: 2NOx → xO2 + N2 Oxidation of carbon monoxide to carbon dioxide: 2CO + O2 → 2CO2 Oxidation of unburnt hydrocarbons (HC) to carbon dioxide and water: CxH2x+2 + [(3x+1)/2]O2 → xCO2 + (x+1)H2O. These three reactions occur most efficiently when the catalytic converter receives exhaust from an engine running slightly above the stoichiometric point.

@@AskArthur it does allow the car to burn more fuel because of it's increased efficiency and compliance with air quality laws. So I think you are correct in saying it allows it to go faster. With out it, you legally wouldn't be able to produce as much power.
Mr.chang cooler Well of course, but I was talking about the reason someone would use calories instead of joules. I'm not even a chemist so I'm not going to be very good at this in the first place.
They make cars go slower. A converter is a big restriction on the exhaust system robbing your engine of power. It's only function is for environmental reasons, just dead weight as far as going fast is concerned, anybody after performance will ditch them.
Well to address the video, Cats dont remove to much power, its more a myth young hooligans believe. Easily tested with devices such as Flowbenches. Also he states "for life", Cats can also fail with engines, snowball effect from when stuff like bent valves happen.
Helps cars to go so fast? I don't really understand why the post-engine exhaust system would affect vehicle speed. Are you possibly thinking of a turbo or did I miss a detail in the vid? Nice vid though, I got here from Cody's channel

But what makes certain elements like platinum have a high affinity for others like hydrogen? And why doesn’t this affinity make them form a permanent molecule?
Does hydrogen-platinum bond really exist? Is it coordinate covalent bond? What’s the relation between hydrogen atom and platinum atom? It sounds more like coordinating
I thought that the platinum catalyst is made to reduce the amount of carbon monoxide (which is very toxic) by further oxidizing it to form carbon dioxide (which is less toxic). Please currect me if I'm wrong.
Omer Magen you are correct. I made this video in a bit of a rush, and so I accidentally said that and I didn't mean it. I made a different video to correct myself on it, but it was unlisted because I didn't want to re-upload a video that was almost exactly the same. I am now thinking I should delete this one and publish the other one...
I don't understand UA-cam very much, but i think you can add notes on a video even after you publish it. Try sticking a note on that part of the video to currect it.
Arthur, your channel has really good content. I think you could make it better by having better editing skills (Mainly when you zoom in pictures and they loose resolution, it's somewhat disconforting) and also better filming angles (For example, you were just too close to the camera in the beggining of the video). I see you're trying (and sometimes you get it right and it looks almost professional) and I hope you can improve your channel more and more. Keep trying! Thanks for sharing your knowledge with us!
Thanks! Yes, you are right, I could work on many aspects of my videos, and I will continue to try to improve as I go on. This was just a quick video I made just before I went to get ready to go street mining with Cody, and so some parts were not the best. I will definitely take your advice in future videos!

I thought it would be more understandable, since I know most of Cody's viewers are from the USA, and the USA uses Calories, not joules. However, you are right, joules are the international scientific standard energy unit, and so I will be using joules in future videos.
Sorry. You got it wrong. This is not why catalyst works. You definetly have heard a few things, but apparently have not quite understood it. Catalysts do NOT change the energy for breaking or creating bonds. This is fundamentally wrong! Catalysts have no effect on thermodynamics: The energy change to break or create a bond with or without a catalyst is exactly the same. Cataysts do change the activation energy (you got that right), but the activation energy is not the energy required to break bonds. Then, a Pt catalyst does not make a car run fast, this is really nonsense. The Pt catalyst in a gasoline car helps to burn off some residual fuel and poisonous carbon monoxide in the exhaust, thus reducing harmful emissions.. But the catalyst has, in principle, no effect on theperformance of the engine, and therefore does nothing to make your car go fast.
@@arthurtao6820at 0.35 it literally is said that a catalyst changes the energy to break the bond. That is a statement of thermodynamics 1 st law. Catalysts do not change thermodynamics! So your statement is wrong, as I said. The given explanation is confusing binding energy with activation energy. Activation energy is a term related to the rate of a reaction, but that has not so much to do with the binding energy, it is something else. Activation energy is the difference between an initial state and a (hypothetical) transition state, marking the point of highest energy along a reaction path. That energy can be higher or lower than the binding energy, dependent on how the reaction works. Catalysts lower activation energies by providing alternative reaction paths as compared to non'-catalyzed reactions.
it's been 8 years and still one of the best explanations I could find
Yes
Your voice is fascinating

This video was very helpful. I loved the platinum example.
excelent explanation ! i didnt know this until now.
Please forget it agian. It's wrong.
Are there any materials that resemble platinums catalytic properties with hydrogen? I am trying to find a substitute for a hydrogen fuel cell
Why did you use calories? Usually in chemistry they use joules.
BIOchemistry.
Actually organic chemistry. Not the same thing.

sir please put a link in the description for those using cell phones
Great video! Really well explained
Except that it is wrong....
How do you figure a platinum converter makes a car go fast? Their use is to reduce nitrogen compounds in the exhaust gases to reduce air pollution.
Without the platinum converters, engines would need to be much smaller for environmental reasons, so in a roundabout way it sort of does.
That's really "roundabout".
+uTube486 we could say that it makes cars go fast, holding the environmental impact of the vehicle fixed.
They make cars go slower. A converter is a big restriction on the exhaust system robbing your engine of power. It's only function is for environmental reasons, just dead weight as far as going fast is concerned, anybody after performance will ditch them.

So oxygen has more affinity towards hydrogen than platinum has with hydrogen, thus platinum does not get used?

Catalytic converters don't make cars go fast! And generally, contain a few more metals than just platinum. Good video though, keep it up
Agreed, your Catalytic converter actually makes your car slower (be restricting exhaust flow) and not go fast
