Greater the a value more will be non ideality ...
In case of polar a is directly proportional to strength of bond
In case of non polar a is directly proportional to molar mass ..
Same as b ..
So greater the a and b values more will be non ideal behaviour ❤

Sir amazing lecture ...❤

Why is the excluded volume of 1 mole of gas 4 times its molar volume ? Plz explain

[@sadamsid8940]

Ans mile to mjhe batana

[@razasiyal1913]

I think jis... gas molar mass will more as well as size more when size of gas molecules greater then attractive forces more So volume Kam ho ga due to attractive force with more Molecular mass beacuse.
n=kV
M=size of molecules and attractive forces.
Molecular Attractive forces is inversely proportional to " V"

[@a.bgamerz3749]

Excluded volume is the volume around the gas molecules while molar Volume is one which is occupied by one mole of gas molecules . Excluded volume is inaccessible to other molecules because of their finite size and repulsive forces. It means that around each volume there is a sphere of exclusion (Ve) .
That's why it is 4 times higher

[@UsmanUsman-f1r]

Excluded volume is vol occupy by all four sides

[@EagerMonarchButterfly-up9iy]

Acha to diameter Jo aik molecule ka doisray molecule say 300 gunna zayada hota wo kaisay hota hay jis tarah wo hay is tarah ye hai

doesn't the molecule B strikes with walls of vessel or it only attracting A molecule?

[@AhmadKhan-lx4so]

It only attracts A molecule

Acha excluded volume wo hamary pas hota hai 4 times molar volume of gas kun k yar daikho agar high pressure hum ny apply kia hai to us ka actual volume bhi hai to jitna high pressure ka jo volume tha usko 4 parts mai divide krain to to jo 4 part hoga jisky under actual volume hai wo hamary pas excluded volume hai to isy waja sy hamary pas jo excluded volume hai actual volume or molar volume k 4 guna hai
