Question

For a gas having zero intermolecular forces, Write the vander waal equation.

Answer 1

Solution:-

Van der waal's equation for a gas-

$(P+\frac{a{n}^2}{V^2})(V-nb)=nRT$

Here $a$ and $b$ are constants.

The constant $a$ for the intermolecular force between the molecules and the constant $b$ accounts for the molecules occupy some space of the container.

For a gas having zero intermolecular force,

$a=0$

$\therefore$ Van der waal's equation will be-

$(P+\frac{0\times n^2}{V^2})(V-nb)=nRT$

$\Rightarrow P(V-nb)=nRT$

Hence for a gas having zero intermolecular forces, the vander waal equation will be-

$P(V-nb)=nRT$
