A new pesticide is found to be resistant to degradation by H₂O unless it is acid or base catalyzed.

a) Using the laboratory data above, calculate how long will it take for a solution containing 10 ppmof pesticide to degrade at a pH = 8.2 (the pH of ocean water) to the regulatory limit of 5 ppb?

Report your answer in units of hours and enter it as X.Xx10(X) or X.Xx10(-X)

b) What is the final pesticide concentration using the time calculated in part a if the aqueous system is rain water with a pH = 5.5 and C_o = 10 ppm?

Report your answer in units of mg/L and enter it as X.Xx10(-XX)
