The compressibility factor for a real gas at high pressure is .

Options

A. `1`
B. `1+Pb//RT`
C. `1-Pb//RT`
D. `1 +RT//Pb`

Explanation

For real `(P+(a)/V^(2))(V-b)=RT`
At high pressure `P gt gta//V^(2)`
Thus neglecting `a//V^(2)` gives
`P(V -b) =RT` or `PV =RT +Rb`
`(PV)/(RT) =Z =(RT+Pb)/(RT)`
`Z =1 +(Pb)/(RT)` .
