If we consider a system to undergo an irreversible process from state 1 to state 2 and a reversible process from state 2 to state 1, then through Clausius inequality
∫21δQirrevT+∫12δQrevT≤0
∫21δQirrevT+S1−S2≤0
S2−S1≥∫21δQirrevT
ΔS≥∫21δQirrevT
Does this mean that the entropy change for a reversible process is greater than that of an irreversible process? I'm convinced I am wrong because my notes say otherwise but isn't Δs the entropy change of a reversible process and (∫21δQirrevT) the entropy change of an irreversible process?
