coe-kit (10 pts) Two pesticides, aldicarb and atrazine, are applied to a field in equal amounts. The pesticides decay independently by a first order reaction described by c = Note: the reaction rate, k, for each pesticide is different. The soil was tested 30 days after application and the relative concentration, 0.70. Calculate the half-life of aldicarb if the half-life of atrazine is 60 days. Hint: as a starting point, write the equation Caldicarb = Catrazine Caldicarb for concentrations as a fraction with different rates Catrazine Coe-kft Coe-kg't
