Question

The rate of a chemical reaction can be measured as the rate of appearance of any of the products or as the rate of disappearance of any of the reactants. These relative rates of reaction are related through the stoichiometry of the overall reaction. For example, the rate of the reaction shown below can be determined by measuring the initial rate of disappearance of I, -A[I/At. Cl03-(aq) + 91. (aq)+ 6 H+ (aq) → 31.3 (aq) + Cl-(aq) + 3H20 If the initial rate of disappearance of I under a given set of experimental conditions is 46.1x 10-3 M/s then what is the rate of appearance of I3 under those same experimental conditions? Enter your answer with units 23.1e-3 M/s The relative rates for the disappearance of reactants and products is determined by the stoichiometry of the reaction. The relative rates would be given by: -1/2 Δ[A]/At =-1/3 Δ[B]/dt = + Δ[C]/At If Δ[C]/at= 0.5 M/s, then 0.5 M/s = + Δ[C]/At =-1/3 Δ[B]/At 0.5 M/s =-1/3 Δ[B]/At B will disappear at three times the rate that C appears, as indicated by the stoichiometry.
