Chlоrine is аdded tо а wаter stоrage tank for disinfection. The volume of the tank is 10 liters. The decay of chlorine in a distribution system follows a zero-order decay with a rate constant of 3.60 mg/L-hr. If the concentration of chlorine in a well-mixed water storage tank is 8.00 mg/L at time zero, what will the chlorine concentration be after 2 hours? Assume no water flows out of the tank.
