Final answer:
We cannot calculate the reaction rate at absorbance 0.50 in Experiment 2 without additional information.
Step-by-step explanation:
The question asks to calculate the reaction rate at absorbance 0.50 in Experiment 2. To do this, we need to convert the initial linear rates to units of M/min using Beer's law and the molar absorptivity for the colored product. Unfortunately, the necessary information to perform the calculation is not provided, so we cannot determine the exact value for the reaction rate at absorbance 0.50 in Experiment 2.
