Purpose: The purpose of this experiment is to determine the enthalpy change for the decomposition of aqueous hydrogen peroxide using iron (III) nitrate as a catalyst by constant pressure calorimetry. Procedure: Composition book pages 27-28 Data: See attached Calculations: Summary of Results: Calorimeter: #22 Sample Identity: H 2 O 2 Experimental H Δ decomp (kJ/mol): Trial 1: -72.295 Trial 2: -78.974

Unformatted text preview: in the decomposition of hydrogen peroxide using a catalyst to speed up that decomposition. The catalyst was iron (III) nitrate. This was achieved when two trials were done using calorimetry to determine the heat loss. Some sources of error could include calculations and not bringing those calculations out to the right amount of sig figs. Another source of error could include measuring the two liquids incorrectly and getting off data because of that. Also using the best fit line on the computer incorrectly and getting the wrong final temperature....
