Use the van der Waals parameters for hydrogen sulfide a/(atm dm6 mol-2) = 4.484 and b/(10-2 dm3 mol-1) = 4.34 to calculate approximate values of (a) The Boyle temperature of the gas (by assuming van der Waals gas behavior); (b) The radius of the hydrogen sulfide in pm based on the argument given on Page 23 in Section 1C where b = 4 Vmolecule NA. Read the definitions on Page 23 in the textbook (atkins physical chemistry 11th edition) (c) Critical temperature Tc (in K) and critical pressure Pc (in atm). (d) Plot the p-V diagram for the hydrogen sulfide van Waals gas for three isotherms: T = 0.85 Tc, T = Tc, and T = 1. 8 Tc where Tc is the critical temperature in the range of molar volume Vm between 0.0600 L/mol and 0.800 L/mol . Show the units and the range in your plot. Note that if you plot the p-V diagram correctly, the equilibrium vapor pressure cannot be estimated, for example, at T = 0.85 Tc.
