The rate constant for the reaction CO + H 2O 2 → HOCO + OH (R1) at 713 K is determined based on the batch reactor experiments of Baldwin et al. [R.R. Baldwin, R.W. Walker, S.J. Webster, Combust. Flame 15 (1970) 167] on decomposition of H 2 O 2 sensitized by CO. The ...

The most general theoretical approach to estimate the rate constant is the search of transition state with utilizing high level of ab initio calculations [16], [17], [18]. However, such calculation is computationally too expensive to apply to the large size compounds. Alternatively, the computati...
where r″ is the particle reaction rate per external surface area (masscarbon m−2 s−1), kr is an Arrhenius rate constant: (6.10)kr=Ar exp(-ERT) and PO2,s is the partial pressure of O2 at the particle surface. This rate equation is a global, first-order expression that is ...
The value of Kd (deactivation rate constant, see its expression in the “reaction analysis” section) and the initial selectivity at 10 h were 0.0421 h−1 and 96.0%, respectively. In general, the deactivation of DDH reaction was attributed to the sintering of Pt NPs with large Pt...
An analytical formula was obtained for the rate constant; calculations using this formula require the solution of a cubic equation. Analysis of the results shows that within a certain interval of parameters, non-Markov character is not manifested; i.e., the rate constant of the process is very...
The discovery of highly enantioselective catalysts and elucidating their generality face great challenges due to the complex multidimensional chemical space of asymmetric catalysis and inefficient screening methods. Here, we develop a general strategy fo
The global attractiveness of the constant positive steady state and the explicit formula of 0 are obtained when the space is homogeneous. Simulation results reveal that the spatial heterogeneity can enhance the spread risk of the disease. It is found that the distribution of infected individuals is...
Bio-orthogonal click chemistry based on [3 + 2] dipolar cycloadditions has had a profound impact on the field of biochemistry and significant effort has been devoted to identify promising new candidate reactions for this purpose. To gauge whether a prospective reaction could be a suitable bio...
