Q2) since pressure is low so pressure correction n²aV² can be neglected.

So equation becomes, P(V - nb) = nRT Dividing by nRT througout we get,

PVnRT - PnbnRT = 1,

Z - bRTp = 1,

Z = 1 + bRTp ................which is option(b)

(not sure of the ans.)

i think since pressure is low, then volume is high.. so volume correction will be neglected...

??

nicely explained...

i was thinking all the time it was monobasic acid....

yes agree with Asish volume correction shud be neglected wen volume is very high
@Manmay we say 1 + α ≈ 1 wen α < < 1 ..so since volume is high so an²/V² will be low and presuure is also given very less..so we cant neglect it..

then what should be the answer govind??

btw solved the first one?

ya. sorry i did the opposite thing.
So by neglecting Volume correction I guess ans will be (d)
