A system undergoes a process in which the entropy change is +5.51 JK-1. During the process, 1.50 kJ of heat is added to the system at 300 K. The correct information regarding the process is
Options:
Answer:
B
Solution:
q/T = 1500/300 = 5.00 J/K. The entropy change is 5.51 J/K, so Δ S > q/T. Clausius: Δ S ≥ q/T with equality only for a reversible path, so the process is irreversible. Matches (b).
