You use a container with 100 mL of water to measure the mass transfer coefficient, k, of a highly potent drug Eitecillin dissolving in water. The system involves a 5.0 cm diameter disk of compressed pure Eitecillin that has one face exposed to the water (see diagram). The temperature and agitation of the water are carefully controlled. You measure absorbance of the solution in order to obtain data on the concentration of Eitecillin dissolved in water with time (see Table). Calculate the mass transfer coefficient for these conditions. The solubility of Eitecillin in water at this temperature is 32.2 mg/L. Absorbance Measurement Eitecillin Data Time (s) 20 70 120 Eitecillin (mg/L) 9.6 19.7 24.5
