Chemistry - Real Gas Question with Solution | TestHub

For the gas A , $\mathrm{a}=0$ and its dependence on P is linear at all pressure

For the gas $\mathrm{B},\mathrm{b}=0$ and its dependence on P is linear at all pressure

For the gas C, which is typical real gas for which neither a nor $\mathrm{b}=0$.By knowing the minima and the point of intersection, with $\mathrm{Z}=1$, a and b can be calculated.

At high pressure, the slope is positive for $C$ gas.
