6. (15 points) The van der Waals (vdW) equation of state is used to estimate the pressures and volumes of real gases, and it is given by a RT P= V b = V = where V is the molar volume (L/mol), b is a correction due to the volume of the molecules and a is related to the molecular attractive interactions. The gas constant is R=0.08206; L'atm/(mol.K), and T is the tempera- ture (in Kelvin, K). The values of a and b depend on the type of gas; some values are given in the table below. Write a matlab function using the switch structure that computes the pressure P using the vdW equation of state. The function's input arguments should be T, V and a string variable containing the name of the gas listed in the table. Test your function for chlorine (C12) for T 300K and V = 20 L/mol. = = Gas Helium, He Hydrogen, H2 Oxygen, O2 Chlorine, Cl2 a (L'.atm/mol) 0.0341 0.244 1.36 6.49 b (L/mol) 0.0237 0.0266 0.0318 0.0562
