Regarding the van der Waals constant which of the following is/are correct?

Options

A. `''a''` depends on the intermolecular interactions
B. `''b''` depends on the size of the gas molecules
C. `''a''` and `''b''` are the characterstic constant not the universal gas constant
D. All of the above are correct

Answer

D

Explanation

In van der Waals equation `(P+(am^(2))/(V^(2)))`
`(V-nb)=nRT`
`''a'' & ''b''` are the characteristic constant not the universal gas constant and depends on the intramolecular interactions and size of the gas molecule respectively
