2. Hydrogen iodide, HI(g), decomposes into hydrogen, H2(g), and iodine, 12(g), when it is irradiated with 207 nm light. If the irradiation is done with a 90 W lamp (100 % efficiency) for 0.01s, 442.8 μg of HI are decomposed. What is the approximate integer quantum yield for the decomposition of HI in this process? A) 3 (1W = 1 J/s and molar mass of HI = 127.9 g/mol) B) 1 C) 2 D) 7 E) 4
