? (2) Analyze the graph and determine the reaction stoichiometry. CH,O(aq) : NaOH(aq) = (3) Using the experimentally determined reaction stoichiometry, write the chemical equation for the reaction between C.H.O.(aq) and NaOH(aq). CALCULATION OF REACTION ENTHALPY Q8. Can we determine the reaction enthalpy, A.H, for the reaction between C,H,O.(aq) and NaOH(aq) from the experimental results? (1) Read the maximum temperature change expected for the reaction from the graph. C (2) Read the volume of NaOH(aq) at the point of the maximum temperature change from the graph. ml (3) Calculate the reaction enthalpy, AH, for the reaction between C,H,O,(aq) and NaOH(aq) from the experimental results. We will assume the specific gravity and specific heat capacity of the resultant solution to be 1.0 g cm and 4.184 J K g', respectively. The calibration constant, K, of the calorimetric system used in this study is K=[ 1 Calculation Reaction enthalpy kJ mol" Compare the calculated reaction enthalpy with the neutralization enthalpy (-56.5 kJ mol at 298 K).
