Experiment 21 Advance Study Assignment: Rates of Chemical Reactions, II. A Clock Reaction 1. A student studied the clock reaction described in this experiment. She set up Reaction Mixture 4 by mixing 10 mL 0.010 M KI, 10 mL 0.001 M Na2S2O3, 10 mL 0.040 M KBrO3, and 20 mL 0.10 M HCl using the procedure given. It took about 21 seconds for the color to turn blue. a. She found the concentrations of each reactant in the reacting mixture...
2. When using the method of initial rates to determine the reaction order of each individual reactant, why must data only be used in which one reactant is changing concentration but not the other reactants? 3. Briefly explain why the number of total drops being mixed in each experiment is kept constant throughout all five experiments. 4. Sketch a molecular‐level picture that illustrates why reaction rate increases when the concentration of a reactant is increased. Note – this might be...
