✦ Synopsis

The Bodenstein approximation for trace-level intermediates is used to reduce multistep reaction-kinetic networks of arbitrary topology and size to simpler forms with only pseudosingle steps between nodes and to derive explicit equations for formation or consumption rates of end members. Networks with nontrace intermediates or steps of higher orders in intermediates must be broken at the respective steps into portions to which the procedure can then be applied separately. A recipe is provided with which rate and yield-ratio equations are readily compiled for networks of arbitrary configuration and complexity. The method is illustrated with an example of a reaction of industrial interest.

## Abstract A new kinetic model for cure reactios has been developed from the concept of nonequilibrium thermodynamic fluctuation theory in which a distribution function relaxation spectrum is used for explaining cure kinetics of polymer–filler systems. It is found that an increase in filler loadin

## Abstract In this work, __ab initio__ molecular orbital methods were employed to study the reaction mechanisms of the oxidation of tin (Sn) with different oxidants, including O~2~, CO~2~, HOCl, HCl, ClO, ClO~2~ and NO~3~, during coal combustion. Eleven key reaction pathways were identified. Altho
