The Van der Waals constants for carbon monoxide are a=1.4541 dm^6 mol^-1. Using the hybrid hard-sphere/r^-6 potential, estimate values for the hard-sphere molecular radius \(\sigma/2\) and the \(c_{6}\) value characterizing the attractive tail of the intermolecular potential. Compare this with the Lennard-Jones values. The critical molar volume of carbon monoxide is 0.09310Lmol^-1. Calculate the fraction of the total volume occupied by the molecules at the critical point. Do the same for STP assuming that carbon monoxide behaves as an ideal gas under these conditions.
