To treat the contaminant estrone in the wastewater, you decided to use an oxidant, permanganate. The reaction is assumed to be occurring in an Ideal PFR. Thention rate follows the first order kinetics and half life is 5 minutes. A) What is the value of reaction rate constant (in min:') B) How much time (hrs) is required to reach 99% removal of estrone! If the wastewater is treated in CMFR with retention time of 2 hrs, how much of estrone in fraction would be remaining!
