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...
