For protein X, you do not know the extinction coefficient of the substrate to calculate the true concentration. Therefore you are planning to calculate the initial rate of reaction as a change in absorbance per unit of time. After you did the experiment, you found that the the straightest portion of your graph is between 0 minute and 1 minute, and the absorbance changes from 0.865 to 0.132 within one minute. Calculate the initial velocity, which will be expressed as min-1.

A student ran a kinetics experiment on an unknown dye to determine the rate law. They plotted absorbance versus time (R 2 = 0.5472), LN(Absorbance) vs time (R 2 = 0.9979), and 1/Absorbance vs time (R 2 = 0.7680). Based on the R 2 values, what is the reaction order with respect to the dye in this student's experiment?
