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 jar and placed in direct sunlight. the following data were obtained at 25 °c: time (min) 10 20 30 40 50 60 ppm br2 2.45 1.74 1.23 0.88 0.62 0.44 (a) determine whether the reaction rate is zero, first, or second order in bromine, and calculate the reaction-rate constant in unites of your choice. (b) assuming identical exposure conditions, calculate the required hourly rate of injection of bromine (in kg per hour) into a sunlit body of water, 25,000 gal in volume, in order to maintain a sterilizing level of bromine of 1.0 ppm. 2. for each of the following sets of reactions, describe your reactor system and conditions to maximize the selectivity to d. make sketches where necessary to support your choices. the rates are in (mol/l·s), and concentrations are in (mol/l)
