Vedclass · Answer

(D) According to the van der Waals equation: $\left( P + \frac{a}{V^2} \right) (V - b) = RT$. At very low pressure,the volume $V$ is very large. Therefore,the term $\frac{a}{V^2}$ becomes negligible and can be ignored. Similarly,the volume correction term $b$ is negligible compared to $V$. Thus,the equation simplifies to $PV = RT$. This implies that at very low pressure,a real gas behaves like an ideal gas. Therefore,the compressibility factor $Z = \frac{PV}{RT} = 1$.

At very low pressure,if the molar volume of $CO_2$ is constant,its compressibility factor is ..........
