Kinetics of Heterogeneous Reaction Processes.
Abstract
There were several major results in this project. We determined the unusual kinetics of simple heterogeneons reactions in which the mobility or velocity of each reactant is drawn from a distribution. We also elucidated the rich variety of kinetics in reactions where particles move on ballistic trajectories. Next, we mapped out the kinetics of a simple catalysis model on a disordered surface. Enhanced reactivity was discovered which arises specifically from the surface disorder. Third, we found surprising behavior in the kinetics and spatial organization of reactants in two-species annihilation, A + B right arrow O, when all particles move in the same direction. We then investigated the coarsening kinetics of a system of growing and competing domains which can be viewed as a toy model of war. Finally, we describe advances in a number of physical realizations of aggregation and annihilation.
