Chemical Kinetics and Dynamics

Chemical reactions correspond to irreversible processes creating entropy. Chemistry belongs to the class of nonintegrable Poincare systems. In general, chemistry is associated with resonances-transitions of quantum states. We have studied some very simple examples of such processes, like decay of an unstable state, in detail. (In such cases, there are always multiple time scales.) We obtain a nonunitary ("star unitary"), invertible, nondistributive operator Lambda (which reduces to the unitary transformation operator U for integrable systems). The explicit form of Lambda depends on the interaction of each species with all other types of molecules in the system including the solvent. The basic property that…
