The disinfection of water is carried out in a stirred tank. The treatment process has water as the input at a rate of 38 000 L/h. The tank carries 3800 L of water at all times. Sufficient chlorine is fed to the water. The rate of disinfection can be described as a first-order reaction with a rate constant of 0.055/min. The efficiency of the system can be expected to be (A) 0.050 (В) 0.25 (C) 0.50 (D) 0.75
