## Homework #7

**1. **Read the paper by Rebenne et al., 1996 ["Aqueous Chlorination Kinetics
and Mechanism of Substituted Dihydroxybenzenes,"
by L.M. Rebenne, A.C. Gonzales & T.M. Olson, __Env.
Sci. & Technol__. 30:2235-2242] and prepare a 1-page critique.

**2. **Use the LFER relationship
developed in this paper to estimate the k_{2}
and k_{3} rate constants for 4-nitroresorcinol.

**3. **Now using the results from
#2, estimate the half-life of 4-nitroresorcinol in a chlorine contactor at pH
7.0. Assume a steady state chlorine
concentration of 3.5 mg/L.
