WebEntropy, reversibility, and irreversibility. The entropy change on going from state 1 to state 2 is given by integrating dS = dq rev /dT from state 1 to 2 to obtain ΔS = S 2 − S 1 = ∫ 1 2 dq rev /T, where T is the absolute temperature. For an irreversible process, we cannot integrate dq irr /T to obtain ΔS because dS equals dq rev /T only for reversible processes.
