DISCUSSION Panere your experimental AH° values for the reactions studied in the lab with the literature Compare mese reactions. If any of the observed results deviate from the literature values by a values ont amount (i.e. > 10%), determine and explain how a source of experimental error would lead to the observed difference in each case Enthalpy of Reaction Data for the Solution Calorimetry Lab The following table should provide all the data you need to calculate the literature enthalpy of reaction values for the reactions studied in the lab today. The lines in the table divide up the data given to (roughly) correspond with what is needed for the experiments performed, although it may be necessary to use a given data item more than once.
