Statement 1: For an irreversible cyclic process in a closed system, Δ Ssurr = 0.
Statement 2: Entropy is a state function.
Options:
Answer:
D
Solution:
Over a cycle Δ Ssys=0 because S is a state function (II correct). An irreversible cycle has Δ Stotal=Δ Ssys+Δ Ssurr>0, so Δ Ssurr>0. I is incorrect. Answer (d).
