These days, theoretical methods and simulations are widely spread in chemical science. However, in secondary and introductory chemistry, students learn little or nothing about such approaches. To introduce simulations at this educational level it is necessary to identify suitable chemical problems and simulation methods that allow setting up concise computer codes. In addition, it is useful to implement simulations in topics which are already part of the regular chemistry curricula. Here, we employ the Arrhenius equation in combination with a simple stochastic simulation method to illustrate how computer simulations can be used in chemistry to get insights in the temperature dependence of the reaction rate constant. The basis for the simulation is a board game, which puts the students in the position to elaborate the mathematical equations for the modeling of kinetics themselves in a playful manner. Such simulation allows students to establish a connection between the reacting system and the particle model. Furthermore, freely available educational programming software makes it possible for students to write their own simulation program based on the game within limited time and effort.

利用Arrhenius方程的博弈和随机模拟为学生建立反应系统与粒子模型之间的联系

如今,理论方法和模拟已在化学科学中广泛传播。但是,在中学化学和入门化学中,学生对这种方法的了解很少或没有。为了在这个教育水平上引入模拟,有必要找出合适的化学问题和模拟方法,以建立简洁的计算机代码。另外,在已经属于常规化学课程的主题中实施模拟非常有用。在这里,我们将Arrhenius方程与简单的随机模拟方法结合使用,以说明如何在化学中使用计算机模拟来了解反应速率常数对温度的依赖性。模拟的基础是棋盘游戏,这使学生能够以一种有趣的方式为数学建模自己的动力学方程。通过这种模拟,学生可以在反应系统与粒子模型之间建立联系。此外,免费提供的教育编程软件使学生可以在有限的时间和精力范围内根据游戏编写自己的模拟程序。
