Consider the Van Der Waals Equation

Consider the van der Waals equation:

A) the van der Waals "a" term is proportional to molecular size and "b" is proportional to the magnitude of intermolecular forces.
B) the van der Waals "b" term is proportional to molecular size and "a" is proportional to the magnitude of intermolecular forces.
C) large molecules tend to have smaller values for both a and b.
D) the van der Waals equation describes successfully describes the behaviour of non-ideal gases.
