For 1 mole of real gas PV = ZRT from graph PV for real gas is less than PV for ideal gas at point A Z < 1 Z=1-(a/ V m RT )

Q. For $1 m o l$ of gas, the plot of $p V$ vs. $p$ is shown below. $p$ is the pressure and $V$ is the volume of the gas

What is the value of compressibility factor at point $A$ ?

$1 - \frac{b}{v}$

$1 - \frac{a}{RT V}$

$1 + \frac{b}{V}$

$1 + \frac{a}{RT V}$

For 1 mole of real gas
$P V = ZRT$
from graph PV for real gas is less than PV for ideal gas at point $A$
$Z < 1$
$Z = 1 - \frac{a}{V _{m} RT}$
