According to the Van der Waals equation:
▪ a = polarity coefficient → accounts for intermolecular forces (IMF)
▪ b = size coefficient accounts for the volume occupied by the gas particles
stronger IMF → larger Van der Waals constant, a
Bigger molecule → larger Van der Waals constant, b
(a) which of these gases would you expect to have the largest Van der Waals constant a?
H2, HF, F2
(b) which of these gases would you expect to have the largest Van der Waals constant b?
H2, HCL, CL2
