Hi I am 13 yrs old and from your application "khan academy" I was and I'm still watching ur vedios about organic chemistry and kinetics and everything! You taught me this & it was really simple and easy! Thanks!
To be fully rigorous, if Energy is measured in Joules, what exactly does a kJ/mol measure? Unless the mol is not really a unit and could be omitted, it seems to me that a kJ/mol can't be just "energy" but something else.
For a reaction, specific rate constant at 283 K is 2.5 × 10-6 L mol-1 s -1 and at 293 K is 4.25 × 10-5 L mol-1 s-1. Compute the energy of activation of the reaction. Please let me know the solution.... M stuck :(
The energy states indicate gibbs free energy instead of enthalpy. Hence, the sign of energy change indicates whether the reaction is exergonic or endergonic, not exothermic or endothermic.
Can u explain me why activation energy Doesn't change with the temperature . I think it must change because at higher temp we need less energy to activate.
higher temperature means higher energy. The KE of the molecules is directly proportional to the temperature... So the activation energy is basically a specific temperature that a reaction has to reach... since u would reach that level of energy by increasing the temperature
wait!! transition state or activated complex formation is what differs collision theory from transition state theory. but you also included it in collision theory. whyy??? someone please make me understand this. I hate Chemistryyyyy
Thank you for your videos. You’re potentially creating thousands, if not millions, of doctors and scientists.
Koi hai?

Thanks!
welcome'
Chemistry, especially physical chemistry, is flawless!! I love it!!
You indeed a genius!!
Any topic I search for in TH-cam u always came top besides your tutorials are precise and succinct.
Khan Academy is the best out there!
deep thanks and big appreciation for Khan Acadamy
I love and appreciate khan academy
explained it in a great way all in one video, thumbs up
Thank you! It only took 10 minutes to learn what I was supposed to learn in 1:20 hours!
I'm so grateful to your explanation. Thankyou
This is really helpful for me indeed❤I love your videos and I love chemistry
This video was SO helpful!!! Thank you so much
how does effective collision work in reactions?

Thanks alot!! I have been trying to understand this topic. This video was the last puzzle🥺🥺. It all makes sense now! God bless you ♥️♥️
So the proper orientation always depends on the product that you'll be making?
great!!!! BIG Like !

Nice one well explained
Best illustration
Thank you so much Sir
The energy states indicate gibbs free energy instead of enthalpy. Hence, the sign of energy change indicates whether the reaction is exergonic or endergonic, not exothermic or endothermic.
Finally understood this graph! thanks
is it always true that both reactants will have the same energy?
thank you so much. It was a great help
it's very good thank you very mauch
Bloody Arab
Um
ismaeil mohammadi are you joking or just racist?
Thanks alot
THANK YOU SO MUCH, SR.!!!
Thank you
GRAH GRAH EVERYTHING K
❤ what you hate,and it will be easy.
i love khan academy omg
I love chemistry😘😘😘

Thank you very much =)
7:17 , The activation energy of this graph is as you say or it is just the upper part of the energy change ?
I love chemistry
I HATE CHEMISTRY
chemistry is love
chemistry is life
Same. And I'm majoring in it.
Yes...chemistry is killing me...
ME. TOO.
You are welcome to go back to cavemen lifestyle
Sound too low.
Thank you so much. LOL

who else got sent here by spero?
I hate chemistry, but this shit is EZ BRUH(after watching this ofc)
elenaa k me too.....
Failing tomorrow
❤ what you hate,and it will be easy.
I love chemistry
THANK YOU
THANK
YOU
