The critical constants are related to the van der Waals parameters by pc = a/27b2, Vc = 3b and Tc = 8a/27 Rb. For ethane, the values of the critical constants are pc = 48.20 atm, Vc = 148 cm3 mol-1, and Tc = 305.4 K. Calculate the van der Waals parameters of the gas and estimate the radius of the molecules.
