If you needed to calculate the “a” and “b” parameters from van der Waals equation of state, what information about the substance would you need? What are the meanings (briefly) of the “a” and “b” parameters?
What will be an ideal response?
To calculate the “a” and “b” parameters from the van der Waals equation of state at a given temperature, you would need the critical temperature and critical pressure of that compound. These two parameters are correction factors that account for the intermolecular interactions between particles (a) and the actual (“excluded”) volume of the particles themselves (b).
