GCSE Chemistry Revision "Catalysts"

[@yashaswar1973]

Freesciencelessons is a catalyst which decreases the Ea of my revision and therefore increases the Rate of my Revision. 😂 Thank You Very Much!

One day they'll turn this man into a robot so he can create science videos forever and all other science teachers will become obselete

[@DasMonke]

They are already obsolete, they manage to drag a 3 minute lesson into 50 - 60.

[@moonlightmando7163]

@@DasMonke in my opinion the only redeeming quality that teachers have, along with many professions (apart from doing their job) is that they are human. They show sympathy and understand students needs. That’s why we aren’t in desperate need for robots as school itself would become monotonous and bland, more so than its already claimed to be. Therefore, actual bad teachers infuriate me since they are no better than a robot, as they fail to do the one thing that human teachers are there for. Arguably, some teachers are worse than robots, but i think we will be holding off using them as its extremely demotivating to have a machine whirr out information. With all this said, i think the use of educational robots/ robotic doctors is inevitable, within the next few centuries at the most. For now, while robots aren’t the best, we will work alongside them, as an aid.

Your right

[@rizwanwaseem7919]

Obsolete*

[@lucaselliott2209]

No they won’t 😊

[@chantel8869]

You're a life saver if I pass my GCSEs you should be ready to take full responsibility thank you!!

[@rileycom9615]

Same Bro just starting triple science GCSES

[@jamessomanader4647]

so did u guys pass?

[@unknownbaby2918]

did you pass

[@g0als.]

Did you pass

[@hamonthunder2740]

Did u pass.

[@herbiedaglish3484]

Let’s be honest this man is the only reason any of us will pass our GCSES

[@j.p.6716]

One word - legend

[@nolimitdennis8730]

I dont know how someone cant get a grade 7 atleast when your vids are here, honestly these are so good im learning the whole curriculum in a day!

[@dylanwarrick5827]

What did you get at gcse for science?

[@amaadyy]

you guys dont understand how underrated and good this guy is. Respect out to him

[@legospidermanoneandonly]

this man has saved countless lives in exams

[@amandaallen1898]

Catalysts are crucial. Good subject chemistry. Always interesting.

[@jazzsxngh8926]

Sean can I just say something, thank you thank you so much I really appreciate your effort into these videos and I just wanted to say that you are a legend when it comes to these things xD

[@64_User]

Explained it perfectly, 10/10

[@Freesciencelessons]

Thanks for the comment. I'm glad that you're finding the videos useful.

[@kevvonkev]

THIS GUY I AMAZING

[@rizwanwaseem7919]

He is an outstanding teacher

[@camerongray7767]

Thanks for the notes, i am studying year 12 chem

[@camerongray7767]

M. Al Well we need to learn about catalysts, and this video told me what I needed to know. So it was helpful. It can be useful for not only specified in the title like and skill can.

[@callum8158]

Cameron Gray I’m doing triple

[@EsotericMedic]

Same here!

[@Koko_Phyozin]

Thank you, Sir. In case the catalyst increase oxidation rate, activation energy of (w/ catalyst) is higher than (w/o catalyst). Can we still regard that this is catalyst, Sir?

[@Ryan-1704]

A catalyst only speeds up a reaction A reaction inhibitor slows down a reaction but you don't need to know that for gcse

[@nooribrahim7868]

Could you please add this to your changes in rates playlist. It isn't there.

[@Freesciencelessons]

Done. Thanks for reminding me. I appreciate it.

[@nooribrahim7868]

Freesciencelessons thank you very much.

[@TodorMilev3]

Congratulations! Very useful and short video. I like videos like this one.😀

[@nathanaellarkum4160]

this is great but does anybody know how to decipher which catalyst is used in any given reaction?

[@rogueedistortion7682]

you dont need to for gcse bozo

[@GangsterDolphins]

Jeez is that you big man

I love finding armys literally EVERYWHERE

[@EducatorSharmin]

What is the main thing about catalysts?

[@Freesciencelessons]

They provide an alternative reaction pathway with a lower activation energy. This increases the rate of the reaction.

[@rogueedistortion7682]

@@Freesciencelessons my bro thats so easy and simple

[@eshfaq2327]

Why doesn't the mass of the catalyst change in a reaction

[@Harshaplayz]

because catalysts don't react, catalysts are not reactants and hence are not used up, he states at 2:18

[@eshfaq2327]

@@Harshaplayz so because they're not being used up the mass won't change?

[@softkookie-ii9ph]

Thank you sir 👑

Thanks Sir

so much more helpful then stupid revision guides. Science final make sense! well kinda
