Problem 7. BrCH2CH2Br (DBE) contaminated an aquifer which is a drinking water supply at a concentration of 200g/L. The DBE is transformed to HOCH2CH2OH(75%) and CH2=CHBr(25%) in a parellel reaction. The groundwater temperature is 5C and has a pH of 7.5. Using the data that is given in the Table, estimate the concentrations of the three compounds in the ground 15 years after the contamination occurred. The activation energy for the reaction is provided in the Table. Assume no further reaction of the products formed and the reaction can be considered as a batch reactor.
