One mole of an ideal gas at T1 = 300.0 K, p1 = 2.4618 atm, and V1 = 10.00 L is isother- mally expanded to V2 = 20.00 L against a constant external pressure of 1.2309 atm. Calculate ∆U, ∆H, q, w, and ∆S. Compare your results for ∆S and q/T and explain whether your results are consistent with the second law of Thermodynamics.
