A gas obeys `P(V-b) =RT` Select the correct statement about this gas .

Options

A. Isochoric curves have slope `=(R )/(V-b)`
B. Isochoric curves have slope `(R )/(P)` and intercept b.
C. For the gas compressibility factor ` =1+(Pb)/(RT)`
D. The attraction forces are overcome by repulsive forces

Explanation

`P(V -b) =RT`
`:. P =(R xx T)/((V-b)) ,Slope = (R)/((V-b))`
`PV -Pb = RT`
`V = (RT)/(P) +b, Slope = (R ) /(P)` and intercept `b`
` Z = (PV)/(RT) = 1 + (Pb)/(RT)`
`Z gt1` repulsive forces predominates .
