A completely mixed flow reactor is used to treat an industrial wastewater. The wastewater contains benzene. The reactor volume is 500 m3 and the volumetric flow rate of the single inlet and exit is 50 m3/d and the inlet pollutant concentration is 50 mg/L. the first order reaction rate constant for biological benzene degradation is 0.2/day. what is the outlet concentration after treatment at steady state
