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. WebSep 19, 2024 · In a reversible process, every intermediate state between the extremes is an equilibrium state, regardless of the direction of the change. In contrast, an irreversible process is one in which the intermediate states are not equilibrium states, so change occurs spontaneously in only one direction. dairy free gluten free pancake mix
