Modeling Chemical Kinetics Graphically

In literature on chemistry education it has often been suggested that students, at high school level and beyond, can benefit in their studies of chemical kinetics from computer supported activities. Use of system dynamics modeling software is one of the suggested quantitative approaches that could help to develop students’ knowledge about chemical kinetics and chemical equilibrium and to remedi...

Stochastic Chemical Kinetics

where k is the rate constant. The stochastic approach to chemical kinetics is concerned with modeling chemical reactions in situations where the assumptions underlying equations of this type break down. In order to illustrate this, suppose that the reaction above is occuring in a drop of water of volume V , which contains only a very small number, say 3, of molecules of I. The kinetic equation ...

Stochastic simulation of chemical kinetics.

Stochastic chemical kinetics describes the time evolution of a well-stirred chemically reacting system in a way that takes into account the fact that molecules come in whole numbers and exhibit some degree of randomness in their dynamical behavior. Researchers are increasingly using this approach to chemical kinetics in the analysis of cellular systems in biology, where the small molecular popu...

Chemical Kinetics of Ethanol Oxidation

Experimental profiles of stable species mole fractions are reported for ethanol oxidation in a Variable Pressure Flow Reactor (VPFR) at initial temperatures of 800-950K and constant pressures of 3 to 12atm. A detailed mechanism for ethanol combustion is developed in a hierarchical manner, and at each level, the newly added portions of the mechanism are tested by thorough comparison of model pre...
