    The compressibility factor for a real gas at high pressure is :   AIEEE  Solved  Paper-2012

    A) \[1+RT/pb\]                         

    B) 1

    C) \[1+pb/RT\]                          

    D) \[1-pb/RT\]

    Correct Answer: C

    Solution :

                 \[\left( P+\frac{a}{{{V}^{2}}} \right)(V-b)=RT\]at high pressure \[\frac{a}{{{V}^{2}}}\] can be neglected \[PV-Pb=RT\] \[PV=RT+Pb\] \[\frac{PV}{RT}=1+\frac{Pb}{RT}\] \[Z=1+\frac{Pb}{RT}\]       ; \[Z>1\] at high pressure
