For a van der Waals gas: (∂Um∂V)=aV2m In this problem, you will compare the change in energy with temperature and volume for N2, treating it as a van der Waals gas. 1) Calculate ΔU per mole of N2(g) at 1 bar pressure and 298 K if the volume is increased by 7.00 % at constant T. Approximate the molar volume with the ideal gas value. a(N2)=1.370dm6⋅bar⋅mol−2 . Express your answer with the appropriate units. 2) Calculate ΔU per mole of N2(g) at 1 bar pressure and 298 K if the temperature is increased by 7.00 % at constant V. CP,m for N2(g) at 298 K is 29.13 J⋅K−1⋅mol−1 . Express your answer with the appropriate units.

For a van der Waals gas:

(∂Um∂V)=aV2m

In this problem, you will compare the change in energy with temperature and volume for N2, treating it as a van der Waals gas.

1) Calculate ΔU per mole of N2(g) at 1 bar pressure and 298 K if the volume is increased by 7.00 % at constant T. Approximate the molar volume with the ideal gas value. a(N2)=1.370dm6⋅bar⋅mol−2 .
Express your answer with the appropriate units.

2) Calculate ΔU per mole of N2(g) at 1 bar pressure and 298 K if the temperature is increased by 7.00 % at constant V. CP,m for N2(g) at 298 K is 29.13 J⋅K−1⋅mol−1 .
Express your answer with the appropriate units.
