Question

vander Waals equation at high pressure for 1 mole is

Answer 1

At higher pressure value of wanderwals constant a becomes zero as due to greater pressure the molecules come closer to  each other and hence the repulsive force dominates

So as a=0

(P+an^2 \ V^2 )(v-nb) =nRT

P (v-nb) = nRT

PV - Pnb =nRT

Dividing throughout by RT

Z-pnb/RT = 1

Z= 1+pnb/RT

As n=1

Z=1 +Pb/RT
