In order to study the photochemical decay of aqueous bromine in bright sunlight, a small quantity of liquid bromine was dissolved in water contained in a glass battery jar and placed in direct sunlight. The following data were obtained and tabulated in Table Q2. Table Q2 |Time (min) | 10 Br2 (ppm) 20 30 40 0.88 50 0.62 60 | 2.45 | 1.74 1.23 | 0.44 Determine whether the reaction rate is zero, first, or second order in bromine, and calculate the reaction rate constant in units of your choice. (a) (b) Assuming identical exposure conditions, calculate the required hourly rate of injection of bromine (in pounds) into a sunlit body of water, 25,000 gal in volume, in order to maintain a sterilizing level of bromine of 1.0 ppm.
