At 25°c is 1245 km h-, the root mean square velocity in m s is in gas phase the ratio of excluded volume to molecular volume for a spherical molecule is a mixtu

sir but we use the formula b=4v

Read this

b= 4v is for per molecule

if nothing is specified what will wr take b=4v or 8v

8v

because collision is bimolecular

please accept my answer Dear

🙏

got it??

hope this will help you

it's 8

yes

my answer is 4

check it sourav

It comes 8

sir but we use the formula of excluded volume as b=4 v

sourav here you have to find ratio of excluded volume to molecular volume

This is illustration of excluded volume in vander waal equation

then what is b=4v and when to use it

https://ask.learncbse.in/t/prove-that-the-excluded-volume-b-is-four-times-the-actual-volume-of-the-gas-molecules/13543 sourav read this these are interrelated

sourav??

sir if nothing will be mentioned we will take b=4 v or 8v?

here for vanderwaal relation you have to go for the diagram shown above and accordingly you take b value

always 2r value sourav

Distance of closest approach

sir, im asking like in the qs is not mentioned if we will take excluded volume per pair of molecule or only per molecule.. in that situation which value we will take

per pair of molecule

now got it sourav??

sir in the booklets there are too IIT JEE qs along with Jam last yr qs.. should i only do jam qs or both?

better you go for both

time management

ty 😊

you're welcome sourav😊

Dear sourav please mark the answer 😊

i cant mark it. app prblm

okk dear sourav no problem...please do this next time😊

i guess this app needs update or something.. hangs a lot.

yes sometym working like a monster....client error,server error showing and sometym reply is deleted after sending
