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-, -D[I-]/Dt. ClO3-(aq) + 9I- (aq)+ 6 H+ (aq) → 3I-3 (aq) + Cl-(aq) + 3H2O If the initial rate of disappearance of I- under a given set of experimental conditions is 81.1 x 10-3 M/s then what is the rate of disappearance of ClO3- under those same experimental conditions?
