At low pressure, the van der Waals' equation is reduced to

Options:

Answer:

Solution:

Van der Waals' equation (at low pressure),

$[P + \frac{a}{V^{2}}] (V - b) = RT$

at low pressure $V_{m}$ will be high

$∴ b$ can be neglected $(P + \frac{a}{V_{m}^{2}}) V_{m} = RT$

${PV}_{m} = RT - \frac{a}{V_{m}}$

$∴ Z = \frac{{PV}_{m}}{RT} = 1 - \frac{a}{V_{m} RT}$
