AbsolutGB Thanks! I am pleased they are helping. Please share the link of the video and follow me on twitter @allerytutors for pre-release info on future videos and developments.
omg thank you!! after consulting my friends, temporary highschool TA, chemistry teacher and 2 other videos, i FINALLY UNDERSTAND after your video!! once i realised the peak is simply the average energy found in a sample of molecules, i finally understood why theres a "hill" in the distribution. thank you so much, saving a chem grade 12 student here! keep up the great videos
Thank you so much Sir! i never got this concept neither by teacher nor by the friends who tried to explain me this.... but the way u taught and u explained just cleared all my concepts and now i am able to solve all questions.. May God bless you! :)
As the area under this curve is constant, surely this graph assumes the situation taken at any exact point in the reaction, and therefore when altering ea and temp, the exact rate at that point in the reaction? Is this true? Also, how to the particles involves in insufficient energy unsuccessful collisions eventually gain enough energy to achieve the ea and become successful, causing all particles to eventually be reacted and causing the reaction to stop?
Hi sir this is a very good explanations but i have a question the peak of the curve representing the sample with higher temperature was lower than the peak of the curve representing the sample with higher temperature does that mean that whenever the temperature increases less molecules have the energy provided by that increase and that more molecules have the lower temperature?
Thank you so much, it helps alot , but why the activation energy start from the right , not from the left , the reaction starts from the left not from the right
+tala jaouni No the graph shows the energy distribution of the particles. The left means low energy the right means high energy. The activation energy is normally high in energy so appears on the right. From the chart you can see that most of the particles have energy lower than the activation energy. Only some have energy greater than the activation energy. Hope this helps!
Loody Nagy Yes we describe the graph as asymptotic (line that never touches the x axis) Maxwell Boltzman curves show the average energy of a fixed number of particles. Some have very little energy, some have medium energy and some have very high energy. Basically no matter how high the temperature (which gives the particles energy) you will always have some particles that have very high energy hence the reason why the curve never touches zero but gets closer to it. In maths terms it only reaches zero at infinity. What a head ache ay!?
There are often exam questions which have a graph with different lines on showing different concentration, pressure and temperature and we have to deduce which line on the graph explains which - these are the questions I find slightly challenging; do you have a video explaining this? Thanks!
+iram khan Hmmm. I know what you mean. I have no videos on that specifically but unit 2 past paper vids may have one of these questions on. I have a few of these for varying exam boards. A Maxwell-Boltzmann curve is in all boards and obviously they mean the same thing so feel free to take a look at them. Hope this helps!
LaLakrs Thanks for your feedback. Please share my channel to others who you think it will help to. You can follow me on twitter @allerytutors to get pre-release information on video releases in the future.
I'm going to scream I just had a panic attack and realised I have 8 and a half weeks till my CIEs and I know nothing at all in any subhect??? wtf have I been doing A also great video thank u sm
That is NOT the average energy!!!!!!!!!! That is the most probable energy, which is completely different, and the AQA specification makes this very clear! do not make the mistake of saying "average energy" when you mean the "most probably energy"!
Great video, brilliantly explained, even as an A2 student resitting this, it's easy to forget bits and pieces of Chemistry!

Thank you so much, for the first time I actually understand The distribution curve!
You're welcome!

Explained so skillfully !
Your videos deserve way more views, really helpful thanks :)
+mavihs26 Thanks very much! It's getting there. 2.5K subs in just over a year is brilliant for me! I am just pleased people are benefitting!
Thank you very much! MCQ's tomorrow! ^_^; Couldn't have gotten through chemistry without your help.

Thank you for making me understand for this topic!
wow your amazing your videos are so helpful thank you
+Flower child Thanks very much! Please spread the word!

Amazing, thank you very much!

Why is the total area under the curve the same? And in exams what does it mean by probable
Why doesn't the end line of the curves (on the right side) ever touch the x-axis?
This video was really helpful though, thanks a lot!

Ugh! Much headache! :$
Thanks a lot though, much appreciated! :)

If the number of particles stays same then why the max point of rtp graph and higher temperature graph are not the same
great video thanks fam

2:53 it is not the average energy of the particles, more like the "majority" energy of the particles. But good video, thanks man
I'm going to scream I just had a panic attack and realised I have 8 and a half weeks till my CIEs and I know nothing at all in any subhect??? wtf have I been doing
A also great video thank u sm
Life saver!

thanks
thanks a lot
Thanks :D
No problem. Please share.
paper 3 today im ready....... to fail
speak fastly so need to be slow
??
He means, you speak too fast. :3
you can decrease the speed of the video
