A toxic compound being is removed from solution in a CSTR at Steady State according to a first order reaction rate. The upstream concentration of the pollutant is 14 mg/L and the downstream concentration is 1.7 mg/L. The volume of the CSTR tank is 3120 m^3. Water is being treated at a rate of 48 m^3/min. Calculate (i) the rate of removal, (ii) the rate constant, and (iii) the residence time.
