Hydrogen sulfide is a poisonous and bad-smelling pollutant. One way to remove it from water is to treat it with chlorine
H2S(aq)+Cl2(aq)--->S(s)+2H^+(aq)+2Cl^-(aq)
Using the following experimental observations, write a rate law for this reaction:
A.) Doubling the concentrations of H2S while keeping the concentration of Cl2 constant results in the initital rate increasing by a factor of two.
B.) Halving the concentration of Cl2 while keeping the concentration of H2S fixed results in the initial rate decreasing by a factor of two.
