Challenge

1) Explore the effects of atrazine degradation if the weather conditions changed over the wetlands. What would occur if the ambient air was saturated and there could be no evaporation? What if it rained, making the evaporation rate a negative value? Choose appropiate values for Q (surface area evaporation) in these two scenarios, and plot them in comparison with the original case using Polymath. You should observe differences on the way the weather affects the molar flow of atrazine, F_A, as the waste water travels a distance of z = 1000 m.
