When the catalyst was at 0.1 mg/mL and the substrate concentration 16 MM, the initial rate of absorbance change was 0.006 absorbance units per second. The measured product has a molar extinction coefficient of 6220 M-1.cm-1, and the path length is the width of a cuvette; 1 cm. Required:
Using the information above, can you rearrange the Beer-Lambert equation to convert the absorbance change of rate into a rate of product formation and select the correct value below?

a. 0.8 M^-1.s^-1
b. 1.2 M^-1.s^-1
c. 1.2 M^-1.s^-1
d. 0.8 M^-1.s^-1
