Work problem 1 again, this time assuming the gas is a van der Waals gas with critical constants PC= 3.64 MPa, V C,m = 280 cm3 mol-1. Assume the same temperature and volume change as problem 1.
*Problem 1 was, calculate the change in the Hemholtz energy when four moles of an ideal gas at 125 degrees celcius undergoes an isothermal expansion from 3.75 L to 8.25 L. (this is problem number one, so when it refers to working problem number 1 again it is talking about this one)
