Determine the Reaction Order for HCl using calculationsdescribed in the Background section. Show yourwork. Note that your answer will probably not be an even wholenumber as it is in the examples, so round to the nearest wholenumber.
B.   Determine the Reaction Order forNa2S2O3 using calculationsdescribed in the Background section. Show your work. Note that youranswer will probably not be an even whole number as it is in theexamples.
