Arrhenius Equation

Arrhenius! The founder of physical chemistry (you now know who to blame when you're cursing physical chemistry). This video looks into the Arrhenius equation, how you can use it to calculate activation energy and the effects on temperature and activation energy in the rate constant k. All useful and potentially a shed load of marks to gain!

I got my teacher to show this in our lesson because even she was struggling having never taught it and half of my class don't do maths and have never come across logs! So thank you!

[jackthickett]

Got a Chemistry exam tomorrow and you are so much better at explaining things than my University Lecturer. Keep up the good work!!!

[amyadamson]

the Mr.Bruff of stem.... thankyou for saving my a level

[PhoenixVert]

Brilliant video, massively helped me as maths is not my strong point! Thank you so much for putting the effort into making this, keep going!

[bonniexwony]

you’re literally the BEST chem YouTube channel THANK YOU FOR THE USEFUL CONCISE VIDEOS

Was havin’ a proper meltdown down about this, but now I don’t feel like an idiot, tah luv

God, I swear this has got harder. Previously, I did my alevels in my sciences over ten years ago, and my dad died, so it just did not work out. I'm 32 and trying again, and I am determined to get the grades I need, but omg, it's really hard. But I'm just going to keep trying, set an example for my daughter. Thank you for all the effort you put into your videos.

Excellent! I've been waiting to see this appear in my sub box, thank you!

[sineadquirke]

Excellent videos, they are all so clear and helpful. Can you explain how you do the whole equation on a scientific calculator, I keep getting a different answer to what you have. Thank you!

Why are the units kj/mol not just kj ? I thought the units for activation energy was just jules or kj

[funnyviralespn]

Thanks so much for the video as you said...came back to watch it :)

I want to marry you! Thanks so much! All your chemistry vids are so useful particularly the longer ones that focus on particular specifications. You have taught me more than any teacher! No shade to my teachers- they're great but you're better.

Brilliant video! Explained it so well thank you!!

[Dangerousbros]

This video was a great help to me thanks! One question, my textbook (OCR Chemistry) has a different simplified equation to yours their's being lnK = -Ea/RT +lnA with the explanation being that the logarithm of two numbers that are multiplied together is equal to the sum of their logs. This has confused me can you explain? Edit: may be a mistake in text book in the rates summary at the end of the section the rate summary there is the same as the version in your video.

[maroofkhan]

In the exam is it fine if we always only use lnk = lnA - Ea/rt. as in the log version of the equation not the normal version cos it’s easier?

[sincj]

@allerychemistry Is the value for [A] always 4.55x10^(13) or does it change? If so, why?

[BliiiiBlaaaaBluuuub]

i think u missed showing us how to work out half life using k equals ln2 divided by 0.5t for 1st order reactions

[Mystq]

How do you find the activation energy?

[nichecritter]

This was super helpful and concise, thank you!!
