The oxidation of iron is an important reaction due to its high economic impact. In this laboratory exploration, the total order of this reaction was determined using commercially available handwarmer packets that rely on the iron–oxygen reaction to generate heat. The active ingredient in the handwarmer packet is iron, which interacts with atmospheric oxygen once the packet is open to the atmosphere. Vernier oxygen gas sensor probes were used to monitor the oxygen in the reaction cell as a function of time. Transferrable skills, such as graphing and data analysis using spreadsheet software, were reinforced during data analysis. The experiment is simple to set up, uses materials that have no known hazards (hence a green chemistry approach), and provides students an opportunity to engage with a commonly used household product to investigate the kinetics of an important and familiar reaction.

铁氧反应动力学的再研究：使用更绿色的方法确定总阶

铁的氧化由于其高度的经济影响而成为重要的反应。在此实验室探索中，使用可依靠铁-氧反应产生热量的市售暖手包来确定该反应的总顺序。暖手器包装中的活性成分是铁，一旦包装向大气开放，铁便会与大气中的氧气相互作用。游标氧气传感器探头用于监测反应池中氧气的时间变化。数据分析过程中加强了可转移的技能，例如使用电子表格软件进行图形绘制和数据分析。该实验易于设置，使用没有已知危害的材料（因此采用绿色化学方法），
