The value of ΔHrxn for Reaction 3 in Part B was determined by three different methods: (1) The "theoretical" value was determined in Step 2 (and Step 6) of the Data Analysis, (2) the experimental value was determined using Hess’ Law of Summation, and (3) the value was obtained directly by measuring the temperature change for Reaction 3. How did these three values of ΔHrxn compare? Was the ΔHrxn obtained in Step 5 of the Data Analysis accurate? Explain. Do the results of this experiment support Hess’s Law?
