(3) (a) Using the First and Second Laws of Thermodynamics, along with the (U appropriate Maxwell relationship, show: (a)r-T (2),-P and that 0 or for a perfect and VDW gas, respectively. (b) Use the expression you derive in part (a) for a VDW gas: 丽. , i. Calculate AU per mole of N2(g) at 1 bar pressure and 298 K if the volume is increased by 1.00% at constant T. Approximate the molar volume as the ideal gas. ii. Calculate AU per mole of N2(g) at 1 bar pressure and 298 K if the temperature is increased by 1.00% at constant V i Compare your answers to part (a) and (b) and make a conclusion about the relative importance of temperature and volume on AU
