AbstractWe investigate the anomalous kinetics in one dimension of a diffusion limited catalytic trapping reaction, A + T → T, by measuring the oxidation of glucose. The reaction is carried out in a thin capillary tube, and the depletion of oxygen in the vicinity of the reaction front is monitored by the fluorescence of a Ru(II) dye. Theoretical results and simulations have predicted an asymptotic t1/2 dependence for the rate coefficient. We observe a depedence on t0.56, with what appears to be an asymptotic behavior approaching t1/2.

ABSTRACTWe study the A + B→B trapping reaction under steady state conditions for the case in which both A particles and traps(B) are mobile. Using Monte Carlo simulations, we follow the kinetic rate law in one dimension. Anomalies arise due to self-organization of the A particles, which results in a slower steady state reaction rate than is predicted classically. We find a partial order of reaction with respect to trap density of X = 2, and an overall order for the reaction of Z = 3.2. These results are in agreement with other works which predict an exponential rather than an algebraic decay law with respect to the A particle density.

In this paper, a system is described in which diffusion of a hydrogen atom takes place effectively in one dimension. The exact differential diffusion equations can be set up and solved, taking into account the possibility of gas-phase removal of the hydrogen atom by a reaction such as H + C 2 H 4 = C 2 H 5 . The collision efficiency of such a reaction has been related to the fraction of hydrogen atoms which reach the oxide layer under certain well-defined conditions. The calculated distribution curves of hydrogen atom concentration throughout the reaction vessel are also given under various conditions.
