Question

how do I calculate literature delta H using the list of reaction provided?

Compare your experimental AH values for the reactions studied in the lab with the literature values for these reactions. If any of the observed results deviate from the literature values by a DISCUSSION significant amount (i.e.> 106), 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 volues for the reactions studied in the lob 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. All enthalpies of formation are for reactions carried out under standard conditions at a temperature of 25°C.
