Examine the difference in the rate of oxidation of TCE and chloroacetic acid (CAA) in double-distilled water versus the rate in a typical natural water. Here, KNOM is 3 x 108 L/mol.s. The NOM concentration in distilled water and natural water are 0.05 and 1.4 mg/L, respectively. The initial concentration of TCE and CAA are 100 and 60 g/L. Estimate QR for each compound in distilled water and in natural water.
