The equation that approximately traces the trajectory in the concentration phase space of chemical kinetics is derived based on the rate of entropy production. The equation coincides with the true chemical kinetics equation to first order in a variable that characterizes the degree of quasi-equilibrium for each reaction, and the equation approximates the trajectory along at least final part of ...

the hcci combustion process is initiated due to auto-ignition of fuel/air mixture which is dominated by chemical kinetics and therefore fuel composition has a significant effect on engine operation and a detailed reaction mechanism is essential to analysis hcci combustion. a single zone-model permits to have a detailed chemical kinetics modeling for practical fuels. in this study a single-zone ...

The kinetics of the pressure induced hydration of modellipid membranes is studied in terms ofthe Avrami-Kolmogorov model and the fractal-like chemical reaction kinetics concept. As a general result, the stretched exponential relaxation function of the

Chemical reactions proceeding on time-scales comparable to or shorter than those of internal rearrangements in the reaction system renewing the environment of reactants (mixing) are, in general, dispersive. For dispersive kinetics, as for dispersive transport and dispersive relaxation, many time-scales coexist, and the rate coefficients, termed the specific reaction rates, depend on time. In cl...

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...

The mechanism by which mechanical force regulates the kinetics of a chemical reaction is unknown. Here, we use single-molecule force-clamp spectroscopy and protein engineering to study the effect of force on the kinetics of thiol/disulfide exchange. Reduction of disulfide bonds through the thiol/disulfide exchange chemical reaction is crucial in regulating protein function and is known to occur...

We discuss, at the mean-field level, the asymptotic shape of the reaction fronts in the general nA+mB → C reaction-diffusion processes with initially separated reactants, thus generalizing to arbitrary reaction-order kinetics the work done by Gálfi and Rácz for the case n = m = 1. Consequences for the formation of Liesegang patterns are discussed. PACS. 82.20.Mj Nonequilibrium kinetics – 82.20....
