Hydrogen peroxide, sodium hydroxide, and dye react together.Stock concentrations of reagents:

NaOH 0.73 M H22

O 1.55 M

Dye 1.00 ? 10-4 M

Reactions mixtures were made as follows. It was observed the plot of ln([Dye]) vs. time in seconds was linear.

Trial NaOH volume (mL) H2O2 volume (mL) Dye volume (mL) Water volume (mL) Slope

1 1.0 1.0 1.0 3.0 -0.114

2 2.0 1.0 2.0 1.0 -0.227

3 1.0 2.0 2.0 1.0 -0.455

A) What is the rate order of the 3 reactants.

B) How long does it take for the concentration of the dye to drop to 3.23 ? 10-5 M if the volumes of each reactant used is 2.0 mL.
