Atrazine, a neutral triazine herbicide manufactured by the Ciba-Geigy group, undergoes biological and chemical decomposition to form hydroxy-atrazine. a).Assuming a pseudo first order decay constant of 0.01/day for atrazinr and 0.005/dayfor hydroxy-atrazine, solve for steady-state concentration of both compontds (A and H) in a rural lake assumed to be completely mixed. Given- Volume of lake=10,000m^3, Qin=Qout=100m^3/day , Cin=10 micro metres
