Suppose a student prepares reaction mixture 2 (see Table below). When the contents of the reaction flasks 1 and 2 are mixed together it takes 75 seconds for the blue color to appear. Reaction Mixture Flask I (250 mL) 0.0010 M Na,3,0, Flask II (125 mL) | 0.10 M HCl 0.010 M KI 0.040 M KBrog Starch HO 10.0 1 10.0 10.0 10.0 10.0 3-4 drops 3-4 drops 2 20.0 10.0 10.0 10.0 3 10.0 10.0 20.0 10.0 3-4 drops 4 10.0 10.0 10.0 20.0 3-4 drops Calculate the initial concentrations of the reactants after mixing. For example, the concentration of S, 03- is calculated as follows. (0.010L)(0.0010 me!)

Suppose that the amount of time needed for reaction mixture 1 to turn blue is 145 seconds. Calculate the initial concentrations of the reactants after mixing for reaction mixture 1 and use the method of initial rates to determine the reaction order, I, with respect to [I). . At
