Question

In the corrections made to the ideal gas equation for real gases, the reduction in pressure due to attractive forces is directly proportional to

• A. $n/V$
• B. $nb$
• C. $\frac{n^2}{V^{2}b}$
• D. $\frac{n^2}{V^2}$

Answer 1

The correct option is D $\frac{n^2}{V^2}$

Pressure correction $=\frac{a{n}^2}{V^2}$
$\therefore$ Pressure correction $\propto \frac{n^2}{V^2}$
