Two options are available in the design of the storage tank for sodium hypochlorite: one tank to hold a 60-day supply or two tanks, each to hold a 30-day supply. The room housing the tanks will have a maximum temperature of 25^oC in the summer. The supplier will provide either 15.89% NaOCl or 7.93% NaOCl. The unit cost ($/Mg of available chlorine) of the more dilute solution is higher than that of the more concentrated solution. The client has indicated that, from an operational point of view, a 60-day resupply schedule is preferable. The decay data for the two solutions has been prepared by a reputable independent laboratory. It is shown below. Use a spreadsheet program you have written to determine the rate constants, and determine the concentration of each solution at 60 days. Analyze the data and make a design recommendation to your client.
