A gas obey P(V-b)=RT which of the following are correct about this gas ?

Answer»

<P>Isochoric Curves have slope `=(R )/((V-B))`
Isobaric Curves have slope R/P and intercept b
For the gas compressibility FACTOR `=1+(Pb)/(RT)`
The attraction forces are overcome by repulsive forces

Solution :`P(V-b)RT`
`therefore P=(R )/((V-b))T`
Slope `=(R )/((V-b))`
`PV-Pb=RT`
`rArr V =(RT)/(P)+b`
Slope `=(R )/(P)`, Intercept =b
`Z=(PV)/(RT)=1+(Pb)/(RT), Z gt 1`.
Hence repulsive forces predominates.
Hence, (A), (B), (C) and (D) are the correct ANSWER.
