COMMENTS Comment on A Linear Chemical Cycle and Oscillations Peter Ruoff StaVanger UniVersity College, School of Science and Technology, Box 8002 Ullandhaug, 4068 StaVanger, Norway ReceiVed: September 4, 2001; In Final Form: NoVember 5, 2001 Suzuki and Morita have in a recent letter1 proposed the idea of building a chemical oscillator on a cyclic array of first-order

reactions. This idea is interesting, but I wish to point out that the irreversible case as considered by the authors is chemically unrealistic, as it violates the “Principle of Detailed Balance”. The principle can be stated in several ways and is described in many textbooks.2 One of its applications is that it explicitely rules out the possibility of a cyclic irreversible process such as that described by Suzuki and Morita.
