For SO2 (g), determine the work at 25 Ā°C:
a) If expanded in a vacuum container.
b) If 4.00 mol is expanded against a constant (atmospheric) pressure in a city at 1200 masl (air made up of 79.00% N2 and 21.00% O2 in mol) from a volume of 10.0 L to 50.0 L. Use standard pressure (1.00 atm).
c) If 4.00 mol is expanded following the Van der Waals model, with a = 6.71 atm * L^2 * mol^-2 and b = 0.0305 L * mol^-1, from a volume of 10.0 L to 50.0 L.
