Formulation of apparent reaction order and its application

  • S. Kagawa


The apparent reaction order αj with respect to component i was shown to be described as αi =∂ lnR/∂lnpi where R and pi are the reaction rate and the partial pressure of component i, respectively. This equation makes it possible to compare the parameters in the power functional rate equation and those in the fractional rate equation with each other. An application was illustrated on a steady-state two-step kinetics.

Кажущийся порядок реакции αi по отношению к компоненту і может быть выражек как αi =∂ lnR/∂lnpi, пде R и pi являются скоростью реакции и парциальным давлением компонента і, соответственно. Это уравнение позволяет производить сравнения пораметров в уравнении скорости, выраженной в степенной форме, с пвраметрами в фракциональных уравнениях скорости. Применение было продемонстрировано в двухступенчатой кинетике стационарного состояния.
