ENHANCEMENT OF GAS PHASE CHEMICAL REACTION RATE DUE TO SIMULTANEOUS PERIODIC TEMPERATURE AND VOLUME PERTURBATIONS

Abstract

A research study was made of the effect of simultane us temperature and volume variations on gas phase chemical systems having well established kinetics. The specific systems selected for study were (1) the decomposition of HI; and (2) the direct synthesis of HBr. A theoretical analysis was made which predicts reaction rate enhancements should occur for systems subjected to periodic perturbations in volume and temperature. The enhancement arises essentially from the non-linear temperature dependence of the rate constants. For a chain reaction such as HBr synthesis, the predicted rate enhancement falls off mildly with an increase in the perturbation frequency. (Author)
