The use of pesticides have allowed agricultural production to increase without an increase in farmed land. Leaching of pesticides from fields into lakes, streams, and the local water table can have detrimental environmental and health consequences. To limit leaching environmental protection regulations require that the half-life of pesticides to be less the 250 days. Report all answers to 3 significant digits A. You are hired to monitor the compliance of pesticides with environmental regulations. You obtain a a pesticide sample with a concentration of 0.2M/L from a local farmer 25 days later you measure the concentration to be 0.19M/L, is the pesticide in compliance with the regulation? Use the formula below: Use the 25 days as the t value and solve for r then subsitute all known values in to find t1/2. Once you find r, find the half-life and compare your t value to 250 days. N(t) = N(0) . ert B) A catalyst can be added to double the decay rate of the pesticide. What is the half-life with the added
