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
Expert Solution
Step 1
We have given that
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 done assuming it behaves as an ideal gas
(b) Calculate the work 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
