Problem 1: A major assumption in the application of the ideal gas equation of state is that the diameter of the molecules/atoms in a system is significantly shorter than the mean free path. For the two cases below, neglecting contributions from intermolecular forces, determine the validity of the applying ideal gas law. Assume a molecular diameter for ethanol (C¿H;OH) of 0.430 nm and 0.505 nm for 1-butanol (C,H,OH). Case 1: ethanol (5 atm, 900 K) Case 2: 1-butanol (200 atm, 500 K)

Use the van der Waals parameters for hydrogen sulfide a/(atm dm6 mol-2) = 4.484 and b/(10-2dm3 mol-1) = 4.34 (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 Vmbetween 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.
