Hydrogen sulfide (H2S) is a common and troublesome pollutant in industrial wastewaters. One way to remove H2S is to treat the water with chlorine, in which case the following reaction occurs: H2S(aq) + Cl2(aq)---->S(s) + 2 H+(aq) + 2 Cl - (aq) The rate of this reaction is first order in each reactant. The rate constant for the disappearance of H2S at 28 °C is 3.5 x 10-2 M-1 s-1. If at a given time the concentration of H2S is 2.0 x 10 - 4 M and that of Cl2 is 0.025 M, what is the rate of formation of Cl - ?
