16. Two moles of a monatomic ideal gas were heated at a constant pressure of 1 atm from 200 K to 300 K. The entropy (S°) for this gas at 200 K is 6.00 J mol⁻¹ K⁻¹. Regarding the related thermodynamic parameters during the process, which of the following statements is correct? (R = 8.31 J mol⁻¹ K⁻¹; ln2 = 0.69; ln3 = 1.10)
(A) internal energy change (ΔE) = 1662 J
(B) work (w) = -831 J
(C) heat (q) = 2493 J
(D) the entropy change (ΔS) = 8.52 J K⁻¹
(E) the entropy (S°) for this gas at 300 K is 14.52 J mol⁻¹ K⁻¹
