Question

State True or False.

The term $V_m-b$ in the Vander Waals equation represents the available volume where molecules of the gas can move.

• A. True
• B. False

Answer 1

The correct option is A True

The term $V_m-b$ in Van der Waals equation represents the available volume where molecules of the gas can move. The actual free space available inside the container for the movement of gas molecules is not the volume of the container but the volume of container minus the effective volume of the molecules. It is equal to $V_m-b$.
