In this lab, we will perform the catalyzed decomposition of hydrogen peroxide under various conditions. We will record the trials using a gas pressure sensor in a lab quest and analyze graphs of the data.
From this analysis, we will determine the rate constant, the activation energy and the rate law.
This started with a tweet. I’m embarrassed how often that happens. Frustrated by a sense of global mispriorities, I blurted out some snarky and mildly regrettable tweets on the lack of attention to climate change in the tech industry (Twitter being a sublime medium for the snarky and regrettable).
