Question

Write the physical significance of van der waals constants a and b

Answer 1

The van der Waals' equation can be written as follows: Significance of van der Waals' parameter 'a': It is the measure of the magnitude of attractive forces between the molecules of a gas. Larger the value of 'a', larger will be the intermolecular force of attraction.

Answer 2

The van der Waals constant 'a' represents the magnitude of intermolecular forces of attraction and the Van der Waals constant 'b' represents the effective size of the molecules.
