4πr² = Total surface area of sphere πr² = Area of cross section of sphere Here, Sir is multiplying the cross sectional area of one sphere to the total number of molecules present at STP. Only the area equal to cross section is occupied by a single molecule while the adsorption is taking place. So it depends on the type of question asked, whether we have to take total surface area or only the area of cross section of the sphere?
Mechanism dekhna bahut important hai kyonki agar polyatomic gas bhi non dissociative mechanism se surface par adsorb hoti h to Langmuir isotherm ka monoatomic gas wala expression hi use hoga. Atomicity ka impact tabhi aayega jab gas dissociative process se adsorb ho rahi ho.
if anyone knows.. just ans. this it's about surface when we draw grp b/w T nd P stret line we get which doesn't start frm origine but here what sir drew started frm origine ....is it correct
Support karo bhai log Sir basic se pdha rhe h aur jitni requirement h utna pdha rhe h
1:24:28 it should be P(int) - P(ext.), please check
Thank you sir....your sessions are always so energetic.... Really amazing revision video.....
sir, bahut easy way me aur kam time me apne itna acha padha diya ... thanku sir
Really very informative session. Thank you so much.
Thanku mam For Extending J Chemistry till sept.. 🤩🥳
Very helpful revision session 😊
Great sir lucky to see your lecture
At 1:12:58 shouldn't area formula be 4πr^2 ?for a sphere? @ #jchemistry
4πr² = Total surface area of sphere
πr² = Area of cross section of sphere
Here, Sir is multiplying the cross sectional area of one sphere to the total number of molecules present at STP.

Thank you sir
Mam, he is a nice teacher. My humble request, please give him a salary increment. 😊
thank you sir,very helpfull video
Sir 1:58:50 mai jo aapne formula likha hai.
Jyoti mam ne usme BCRT/M*2 likh waaya hai
BRT/ m*2
Very nice explanation Raman sir 👍👍👍
In osmometry,RT/M2 multiply with bc??
Same doubt
1:59:16 please check it
Thank you sir♡
Thankyou sir 🌼
Sir Langmuir mei dissociative or non dissociative se nahi dekhenge....
Srf gas ki atomicity se check krenge
Mechanism dekhna bahut important hai kyonki agar polyatomic gas bhi non dissociative mechanism se surface par adsorb hoti h to Langmuir isotherm ka monoatomic gas wala expression hi use hoga.
Atomicity ka impact tabhi aayega jab gas dissociative process se adsorb ho rahi ho.
Thq so much sir
Thank you so much Sir and Jyoti ma'am.💜🌻👌👏
Very understanding video thnku sir 👍👍
Sir..I can't give test..plz help..apka helpline number busy ata hai..
Excellent teaching 👌👌👌
Thank youuu
Mujhe laga Mai bas confuse Hota hu adsorbate and adsorbent pe …. Phir sir ok dekh ke laga eie common hai sayad 25:11 pe dekho
Excellent teaching 👏
Gems of jyoti mam❤️
Thank You So much 🙏☺️ And also Jyoti Mam🙏☺️...
I think 55.52 the delha h formula contains negative sign
Hnji vha pe -ve sign aayega
if anyone knows.. just ans. this it's about surface when we draw grp b/w T nd P stret line we get which doesn't start frm origine but here what sir drew started frm origine ....is it correct
No it's wrong
Amazing
In Young- Laplace eq. ,P(int.) -P (ext.) Aata hai pls check it
Okk I will check it
Sir aap n p ex. - p in. = 2 Surface tension / r likha hai
Pin - P out aaegya sir
????
Yes. You are right
Vry nice session
I request ye intro change krr do 🙏🏼🙏🏼🙏🏼
Bina intro ke bhi kaam chala lenge
He taught very well but this chapter always gave me irritation,it felt like bina koi logic ke sirf formula ratt rahey hai 😥
Pdf kaha milegi ??
👍🏻👍🏻
NYC lecture sir
Sir physical chemistry ka crash course start plz sir
2nd 🥰🥰
Please work on writing that's not clearly visible otherwise everything is excellent 👌.
दोस्त बहोत ही गलतीया है इस,व्हिडिओ मे.ध्यान से देखो पता चलेगी.
34:03 से लेकर 34:22
चेक करो.
👍
♥️♥️♥️♥️♥️♥️
Raman kumar legend of chemistry
At 55:30, minor mistake
1/T2 -1/T1 should be there
First View 😀
Thank you sir🙏
👍🏻👍🏻
