Non-Arrhenius rate constants involving diffusion and reaction

A system in which diffusion and reaction occur is investigated. Explicit results are obtained for the rate constant as a function of position and time. Under certain conditions it is found that the nonequilibrium effects produced by diffusion can lead to a rate constant that differs significantly fr...

Beschreibung
Zusammenfassung:	A system in which diffusion and reaction occur is investigated. Explicit results are obtained for the rate constant as a function of position and time. Under certain conditions it is found that the nonequilibrium effects produced by diffusion can lead to a rate constant that differs significantly from the Arrhenius value.
