Problem 6: Many molecules (chemical contaminants and naturally occuring) can decay from reactions with photons (including from sunlight). Show how to solve Problem 2-17 from your textbook: "Hypochlorous acid decays in the presence of ultraviolet radiation. Assume that degradation occurs according to first-order kinetics and the rate of degradation was measured to be 0.12 day 1 (at a particular sunlight intensity and temperature). Given this, how long does it take for the concentration of hypochlorous acid to reach nondetectable level (0.05mg/L) if the initial concentration is 3.65mg/L
