化学动力学 Chemical kinetics

(重定向自Reaction Kinetics)
碰撞理论预测了反应速率会随着反应物浓度上升而增加。
催化剂对反应历程的影响。催化剂会使反应物经由一条不同的反应途径,以红色标注,而该反应途径的活化能更低,更易发生。

化学动力学也称反应动力学化学反应动力学,是物理化学的一个分支,研究化学反应的反应速率及反应机理。它的主要研究领域包括:分子反应动力学、催化动力学、基元反应动力学、宏观动力学、表观动力学等,也可依不同化学分支分类为有机反应动力学及无机反应动力学。化学动力学往往是化工生产过程中的决定性因素。

化学动力学与化学热力学不同,不是计算达到反应平衡时反应进行的程度或转化率,而是从一种动态的角度观察化学反应,研究反应系统转变所需要的时间,以及这之中涉及的微观过程。化学动力学与热力学的基础是统计力学、量子力学和分子运动论。

Chemical kinetics 化学动力学

(重定向自Reaction Kinetics)
Reaction rate tends to increase with concentration – a phenomenon explained by collision theory.
Generic potential energy diagram showing the effect of a catalyst in a hypothetical endothermic chemical reaction. The presence of the catalyst opens a different reaction pathway (shown in red) with a lower activation energy. The final result and the overall thermodynamics are the same.

Chemical kinetics, also known as reaction kinetics, is the study of rates of chemical processes. Chemical kinetics includes investigations of how different experimental conditions can influence the speed of a chemical reaction and yield information about the reaction's mechanism and transition states, as well as the construction of mathematical models that can describe the characteristics of a chemical reaction.
