those of other students to determine the activation energy for the reaction. The objectives of the experiment are to: • Measure how the light output from a commercial light stick at room temperature varies with time, using a light-sensitive resistor and a digital voltmeter. • Make a suitable plot to determine whether the reaction responsible for the light emission follows 1st order or 2nd...
How to experimentally determine the value of Ea for a chemical reaction The Arrhenius equation was discussed today in class, but I may not have discussed something that would help you prepare for this week’s experiment: how to experimentally determine the value of Ea (activation energy). I will address that here. Basically, the answer to this question (how to get Ea) comes from taking the
