A reactive contaminant decays according to first order kinetics with a rate constant of k. A waste stream containing this contaminant at a concentration of 100 mg/L is treated using an ideal completely mixed flow reactor having a volume 100 L. At steady state conditions, the effluent concentration of the contaminant from the reactor is 20 mg/L. The flow rate of the influent stream is 50 L/hr. The rate constant at which the contaminant decays (k) is
