Graham's Law of Effusion (Diffusion) + Example

How many times faster is Neon than Xenon?
The rate at which molecules travel (on average) is inversely proportional to the square root of their molar mass. Heavier particles move slower.

You're basically famous on youtube. Im in your chem class btw and these videos are very helpful. Thank you!

[@Olena-g7o]

Thank you for explaining how to derive the formula…I am mostly relying on videos right now…Just want to learn some chemistry to help my daughter…Thanks again!…😂

[@AgnesNyamekye-l2p]

I really appreciate the video

[@IsabelRodriguez-nv2ue]

Thank you so very much for explaining this example of Graham's Law. It is truly helpful.

[@nathanielabban9365]

very well explained Sir

[@zhinoadeeb2018]

Thank u so much for this AMAZING explanation

[@jeromeslate3625]

You have confused rate and velocity. The rate of diffusion is mass/time. Velocity is distance/time.

great video

[@dayni2839]

Love the prisoner Analogy I won't forget thatb

[@steven647]

Thanks very helpful. Keep up the good chem vids

[@StraNge-te2wg]

Why is neon treveling faster if the molar mass is bigger than xeon?

[@mitch1285]

For you put Xe on top of the fraction would that then be then amount Xe is slower than He

[@alive3663]

Usually yes but not always

[@falaksharma594]

it helped me a lot..thx

[@ishaanjindal3473]

you are life saver

[@obednathaniel4049]

Bro thanks a lot but the problem am having is I really don't know which has am suppose to take as my R1 and which is my R2 that's why am always having different answers is there any tip you could share that might help

[@lukmanaliyuyahaya]

The element with the smaller atomic number should be the R1

[@aarondelon9454]

Thank you bro.hoping for your next vids

[@khaledahmad7261]

Man, focus with your teacher next time, look at me, I thought i was cool when the teacher was expalining the lesson and I was playing with my phone and not paying attention , and now am out here searching for vids to help me

Sir what to do if mass ratio is given too?

thats it? it was that easy? damn,

[@irfanabinsyk8315]

Thank u 😊 sir

[@michaelparrinello4172]

Good explanation just slow down you are rushing

[@flash_series4898]

if u give me calculater to exam i will get sir but they wont allow na
😐😗

[@uewtv3888]

Please help me with this question.
The density of a gas of relative molecular mass 28 at a certain temperature is 0.90 kgm-3. The root mean square speed of the gas molecules at that temperature is 602 ms-1. Assuming that the rate of diffusion of a gas is inversely proportional to the square root of its density, calculate the density of the gas standard temperature and pressure if its root mean square speed at is 490 ms-1.

[@ivanquiroz804]

Bro less hands

[@brxyann]

Wtf did you mean about the diffusion thing... I understood effusion perfectly but you left me confused on diffusion. Next time spend more than 5 secs talking about it thanks

[@pewkapuw8943]

diffusion is pretty much just the movement of molecules such as say (X) from a high concentration of (X) to a low concemtration of (X)

That explanation of the proportion between rate and mass with Newtonian physics was helpful
