Each liquid has has a characteristic vapour pressure depending upon the nature of liquid ..means liquid having higher magnitude of intermolecular forces will have lesser tendency to escape into the vapour phase and have lower vapour pressure ...eg CCl4 has greater vapour pressure than H2O becox of London interaction (weak interaction).
Mole fraction is the no. Of moles of any component divided by the total no. Of moles in the solution ....look if Mole fraction i.e... moles of one component in a solution increase then moles of other component in that solution will decrease .....now in the graph when u go frm left to right mole fraction of B i.e moles of B increases ...if no. Of moles of B increases then no. Of moles of A decreases because they are the components of the same solution that is why mole fraction of A decreases
Mole fraction is a ratio: .no of moles of A/(no. of moles of A + no. of moles of B). If we have 10 moles A only, its a pure solvent. If we add 1 mole of solute B, then mole fraction (mf ) of A is 10/(10+1).if we add 2 moles of B, mf of A is 10/(10+2), if 3 moles of B, mf of A will be 10(10+3) and so on. Though the number of moles of A is always 10, as the deno minator increased, or as the number of moles of B increased, mole fraction of A decreased.that is, even though the number of moles remains the same for A, as B is added, mole fraction of A reduced. We have to keep in mind that, the total mole fraction is unity.
Now it got more clear 😌😊
Thank you so much mam... This graph always gave me troubles, but after this video my doubts are clear😊❤
That was so nice , wish I found this earlier , was really helpful and clear . Thank you so much ma'am 😀
I know I'm pretty randomly asking but do anyone know a good website to watch new tv shows online?
@Christian Otto Lately I have been using flixzone. You can find it on google :)
@Kaiden Dominic definitely, I've been watching on Flixzone for since april myself =)
@Kaiden Dominic Thanks, signed up and it seems to work :) Appreciate it!
@Christian Otto Glad I could help :)
I got it... It has proven very helpful to me... great explanation hundreds of claps for u
Very nice explanations
Thank you mam
Very easy..way..to...teach..thanks...
Teaching skill are very nice
Thanks......it gets now clear to me
Graph is not same in ncert, also why pressure of 1component is more than the other
Each liquid has has a characteristic vapour pressure depending upon the nature of liquid ..means liquid having higher magnitude of intermolecular forces will have lesser tendency to escape into the vapour phase and have lower vapour pressure ...eg CCl4 has greater vapour pressure than H2O becox of London interaction (weak interaction).
I hope i made some sense
Why is molefraction of XA=1
XB=0taken in left handside? I would be grateful madam answer my question
Thanks madam bahot asani se bata di
Very nice explanation mam
Tq for the best explanation 👌
Aaj tqk kisi aise nahi bataya tha thankyou mam
Thankyuu so much mam now it's clear 💙
Maam whats the difference between pa and p°a tgen?
Very very thanks mam😊
Why the mole fraction of A is decreasing ?

Nice explain in small time
THANK YOU MAM💗
Maam can you tell u your full name,pls
Best 🙏👍❤️
Tq mam lot of helpfull
Super mam💗💗💗💞💞💞💕💕
Mam kal mera compartment hai ar mujje 5 important question samaj nahi aa rha hai pls tell me
Nice explanation
Thanks mam
Thank u mamm very much
Thanks!!

kya baat hai madam thanks for explaining
Cute teaching mam
Nice english
Thnks mam
Here both Xa and Xb are same so do we come to know that which one is increasing nd which one is decreasing.. Do a wer my questn
I like this ticking m
🙂good
Mam ap bohot aachi dikhti ho or ap mere crush teacher bn gyi ho😅
Sudharja bsdk😂😂😂
Nice ...mam lob u
Hi madam
Thank madam for this good vidio.
mam you supe
Hindi ma sajawoi mam
crazy
Hindi nahi aati kya....................... angrezzzzz😂😂😂
Hindi ma bola karo mdm ji
