Question

Vander Waal's constants 'a' and 'b' are related with..... respectively

• A. Attractive force and bond energy of molecules
• B. Volume and repulsive force of molecules
• C. Shape and repulsive forces of molecules
• D. Attractive force and volume of the molecules

Answer 1

The correct option is D Attractive force and volume of the molecules

Vander Waal’s constants ‘a’ and ‘b’ account for the attractive forces between the molecules of real gases and volume occupied by the molecules due to their size respectively. Both of these parameters are considered to be negligible in case of ideal gases.
