BMED 2110 - Finаl Exаm (quiz 10) Recent reseаrch cоncerned with fuels used fоr jets and airplanes has shоwn that the addition of natural products leads to an increase in the stored energy associated with these fuels. A candidate for this application has been isolated form pine wood. It is a molecule with the structure C10H16 . In order to determine the enthalpy of formation of this unknown molecule it is injected with a rate of 1.36 g/min into a reactor. A second inlet stream is air, which enters the reactor at a flow rate of 32.8 l/min and a temperature of 127 C. The molecule reacts with the oxygen in the air to form CO2 and H2O, the degree of conversion of the molecule is 100% and the reactor loses 133W as heat to the environment. The temperature of the product stream is 1.75*103 K. Calculate the specific molar enthalpy of formation of the unknown molecule for its reference state at standard pressure and Temperature. You might need the following data for your analysis: Properties of the unknown substance: chemical structure: C10H16 density 0.858 g/ml melting point: -63C boiling point 156.85 C Enthalpies of formation: Water(liq): -285.83 kJ/mol Water (gas): -241.82 kJ/mol CO2 (gas): -393.51 kJ/mol Hints: For your calculation you must correctly fill out the NH-table, which is provided below (a copy of this table was sent out prior to the quiz, if you do not have it at hand you may draw your own table. A degree of freedom analysis is not required, however you might use it to your advantage.
