Question:

One mole of a van der Waals gas at 25.0????C is expanded isothermally and reversibly from an initial volume of 0.010 m³ to a final volume of 0.095 m³. For the van der Waals gas, (∂U/∂V)T = a/V²_m. Assume that a = 0.556 Pa m⁶ mol⁻², and that b = 64.0 × 10⁻⁶ m³ mol⁻¹. Calculate q, w, ΔU, ΔH, and ΔS for the process.
