Abstract:
Measuring kinetics of chemical reactions is common in many labs. Knowing the kinetics is essential for testing hypotheses, mechanisms, and optimizing catalytic processes. But the work itself is often time-consuming and labour-intensive. This is especially true when studying Arrhenius relations, which require multiple sets of measurements.
We developed a simple device for measuring the kinetics of gas-producing reactions.  It can give Arrhenius plots with hundreds of data points from a single experiment. In the lecture, I will explain how this device works,and show how you can build one yourself. Then, I will show how these measurements can help us understand the fundamentals of catalytic reactions on surfaces, explaining the empirical observations that Arrhenius made in the 1880s. Finally, I will explain how these new insights can help us design new high-performance catalysts.
