Question

23. Hydrogen sulfide (H2S) is a common and troublesome pollutant in industrial wastewater. 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 Cl-(aq) + 2 H^+(aq) The rate of this reaction is first order in each reactant. The rate constant for the disappearance of H2S at 28 degree C is 3.5 x 10^-2 M^-1s^-1. If at a given time the concentration of H2S is 2.0 x 10^-4 M and that of Cl2 is 0.0025 M, what ?s the rate of appearance of Cl^-? A. 1.8 x 10^-8 M/s B. 3.5 x 10^-8 M/s C. 5.4 x 10^-8 M/S D. 9.0 x 10^-8 M/s E. 8.1 x 10^-8 M/s

Explanation / Answer

Should be

2*(3.5 *10^-2)*(2.0* 10^-4)*0.0025 which would = 3.5*10^-8 m/s
