1. Argon is allowed to expand isothermally (at 298 K) and reversibly from an initial molar volume of 5.0 L/mol to a final molar volume of 11 L/mol. (a) Calculate the work (in units of kJ to 4 sig. figs.) done assuming it behaves as an ideal gas (b) Calculate the work (in units of kJ to 4 sig. figs) assuming it is non-ideal using the van der Waals equation where a = 1.34 atm L2 mol-2 b = 3.20 x 10-2 L mol-1
