Reaction rate is a particularly important research object in chemical kinetics, and it is a measure of how fast a chemical reaction goes. In order to illustrate and clarify the evolution of concentration of a substance involved in the reaction, this paper derives an uncertain chemical reaction equation based on the theory of uncertain differential equation. By using the actual observations, one can estimate the parameters presented in the uncertain chemical reaction equation. As an application, the half-life of reaction is investigated. Finally, a paradox for stochastic chemical kinetics is given.

不确定的化学反应方程式

反应速率是化学动力学中一个特别重要的研究对象，它是衡量化学反应进行多快的一个指标。为了说明和阐明参与反应的物质的浓度变化规律，本文基于不确定微分方程理论推导了一个不确定化学反应方程。通过使用实际观察，人们可以估计不确定化学反应方程中的参数。作为应用，研究了反应的半衰期。最后，给出了随机化学动力学的悖论。
