Rate sensitivity analysis of a model of the Briggs-Rauscher reaction

  • T. Turányi


An updated mechanism for the Briggs-Rauscher reaction (also known as “Iodine Clock” reaction) has been investigated by the principal component analysis of the rate sensitivity matrix. The analysis revealed that five reactions of the 15-step model were redundant. The results of principal component and of rate-of-production analyses together gave an insight into the basic processes of the “Iodine Clock” reaction.

Современный механизм реакции Бригса-Раушера (известной также как реакция “иодных часов”) был исследован с помощью принципиального компонентного анализа матрицы чуствительности реакции. Анализ подтверждает, что 5 реакций из 15и-ступенчатой модели можно считать излишними. Результаты анализа принципиального компонента и скорости получения вместе дают более глубокие представления о механизме реакции “иодных часов”.
