The experimental enthalpy of decomposition of H2O2 was determined using another coffee-cup calorimetry. A sample of H202 solution was placed in the calorimeter and the initial temperature of H2O2 solution and the calorimeter was measured. Then, KI solution was added to the solution to catalyze the decomposition of H2O2 to H20. This resulted to an increase of 16.7°C in the temperature. Determine the experimental enthalpy of decomposition per mole of H2O2 given the following additional information. Express your answer in kJ/mol and in 2 decimal places. moles H202: 0.017 mol Ccal: 54.85 J/°C mass of the solution (mainly water): 33.1 g C, of water: 4.184 J/g°C
