Document Summary
3a(g) a3(g,l) is carried out isothermally and without pressure drop in a pfr at 298 k and 2 atm. As the concentration of a3 increases down the reactor and a3 begins to condense. The vapor pressure of a3 at 298 k is 0. 5 atm. 1 (30 pts) 2) 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. In dilute aqueous solutions, 1 ppm=1 milligram per liter, molecular weight of. Experimental data provides ca vs. time, thus dca dt can be calculated. = k c a ln dca dt.
