A) \[1+\frac{pb}{RT}\]
B) \[\frac{pb}{RT}\]
C) \[1-\frac{b}{(VRT)}\]
D) \[1-\frac{pb}{RT}\]
Correct Answer: A
Solution :
According to Vander waal's equation for one mole of gas\[\left( P+\frac{a}{{{V}^{2}}} \right)(V-b)=RT\]at high pressure \[\frac{a}{{{V}^{2}}}\]can be neglected with respect to P, \[\therefore \]\[P+\frac{a}{{{V}^{2}}}\simeq P\] \[P(V-b)=RT\] \[PV-Pb=RT\] \[PV=RT+Pb\]divided on RT on both side, \[Z=1+\frac{Pb}{RT}\]You need to login to perform this action.
