When pressure is low $$\left[\mathrm{P}+\frac{\mathrm{a}}{{\mathrm{V}}^2}\right](\mathrm{V}-\mathrm{b})=\mathrm{RT}$$ or $\mathrm{PV}=\mathrm{RT}+\mathrm{Pb}-\frac{\mathrm{a}}{\mathrm{V}}+\frac{\mathrm{ab}}{{\mathrm{V}}^2}$ or $\frac{\mathrm{PV}}{\mathrm{RT}}=1-\frac{\mathrm{a}}{\mathrm{VRT}}$ $$\begin{array}{l}\mathrm{Z}=-\frac{\mathrm{a}}{\mathrm{VRT}}\\ \left(\because \frac{\mathrm{PV}}{\mathrm{RT}}=\mathrm{Z}\right)\end{array}$$
