KInetics: Transition State Theory

This video discusses transition state theory and energy diagrams. Catalysts are also discussed in the context of energy diagram manipulations. Videos made by Clarissa Sorensen-Unruh on CNM Glass.

Your handwriting perfect and information is so helpful! Thank you for explaining everything so clearly! Please keep making video's!! Thank you again!!

[@tremeramcbean3719]

Thank you so much for this!! Also I'm fascinated that you're writing backwards as you explain this information

[@TechsavvyScientist]

Tremera McBean she probably just flipped the video horizontally

[@nedaq8530]

u made this SO easy to understand thank you!!!

[@gautampatil8945]

your way of explaining is awesome

[@fatema2000fh]

This made so much sense- thank you so much!

[@BelkheirHammouti]

Amayzing ; Thanks so Much for high Quality

[@liquidpaint2648]

Now I cleared that part Thanks

[@merkive]

damn u writing backwards is amazing

[@duckiie15]

THANK YOU!

You just saved my homework 🌈

Thanks🌹💕

[@anmolsharma9143]

Thanks mam It was very helpful 👍☺️

[@emmousa8353]

Thanks alot!

Awesome But I wanted to know is there any possibility that after attending the transition state the reactants fall back, if it do then why? Also if it doesn't then what are the reasons. In ur term if I travel in a rolar coster after reaching the top what are the probabilities that I can fall back

[@csoren1]

Sofiqul Islam Indeed, the transition state is just the theoretical “visualized picture” of the middle of the reaction. So if the reactants’ “reacting” atoms do not have the correct orientation or the energy to overcome the activation energy, then the reaction will approach the transition state and then fall back into the reactants. If the reactants’ atoms have both the orientation and the energy to overcome the activation energy, then reaction will go through the transition state into products.

@@csoren1 thank you ji.

What has the catalyst led to the changes of the energy diagram?

[@csoren1]

Joef Ilomo I’m not sure what you’re asking here, Joef. What changes are a result of the catalyst? Or why has the catalyst led to the changes? Here’s a thought - remember that transition state theory is coupled with collision theory. Atoms within molecules must have the correct orientation and must overcome the activation energy to result in products. The transition state is just the theoretical “picture” of what the reaction looks like in the middle...

[@csoren1]

So, a catalyst helps the reactants obtain the correct orientation faster or lowers the energy of the rate-limiting step so that the reactants can actually overcome the activation energy. The catalyst does the latter by cutting a fewer step reaction into more steps.

keep making videos

[@kendalljones3556]

wow

[@chloema7500]

Is she writing backwards???

[@visheshgoyal9654]

mirror image of actual video

[@lollsazz]

No. You need to think longer about this: she IS writing backwards

[@brittneycrawford2129]

i came to the comments just to find this out lol

[@dionvh]

How is this possible? Is she really writing backwards?

[@EZpZeero]

MY EARS when she writes on the board it screeches lol.
