That's what I've thought. It can be proved by determining entropy through a reversible cycle. However, in class, it was mentioned on an assignment that the delta S is negative and not spontaneous. Which again, does not make sense

Why does there tend to be disagreement on an irreversible adiabat entropy determination? Doesn't an irreversible adiabatic expansion increase the entropy of a system by the Clausius inequality?
