The determination of reaction rate and activation energy is a fundamental experiment for freshmen majoring in chemistry, serving as a critical component of inorganic chemistry laboratory courses and closely aligning with theoretical concepts in inorganic chemistry. Guided by the Chemistry “101 Plan”, this study introduces innovative improvements to the traditional experiment by integrating semi-microscale design, collaborative teaching, and information technology. These modifications aim to achieve the following objectives: (1) foster environmental awareness through reduced reagent consumption, (2) enhance teamwork skills via collaborative problem-solving, (3) develop digital literacy through data processing technologies, and (4) strengthen problem-solving abilities by applying theoretical knowledge to experimental challenges. Through iterative discussions and validation of the Arrhenius equation for data analysis, students not only deepen their theoretical understanding but also cultivate a scientific mindset for addressing practical problems. This approach promotes rigorous scientific attitudes and lays the groundwork for training top innovative talents in chemistry.
