1. Determine the Reaction Order for HCl using calculations described in the background section. Show your work. Note that your answer will probably not be a whole number as it is in the examples, so round to the nearest whole number. 2. Determine the Reaction Order for Na2S2O3 using calculations described in the Background section. Show your work. Note that your answer will probably not be a whole number as it is in the examples. 3. Write the rate law for the reaction between HCl and Na2S2O3. 4. Describe sources of error in this experiment?

A student used a pH meter to collect data for the titration of an unknown concentration of propanoic acid with a 0.150 mol/L solution of sodium hydroxide. The data table from the investigation is shown in the table below. Data for the Titration of Propanoic Acid with Sodium Hydroxide Volume of propanoic acid: 25.00 mL [NaOH] = 0.150 mol/L Volume of NaOH (aq) added (mL) 0.00 2.00 4.11 7.98 11.95 14.08 16.05 17.00 17.21 17.39 17.62 17.99 18.18 18.39 18.80 20.00 22.03 PH 2.83 3.84 4.20 4.64 5.03 5.27 5.61 5.90 6.00 6.09 6.23 6.74 8.80 10.92 12.24 12.56 12.69 Adobe 4343625416 00..
