The standard free energy of formation, AG? , of a substance is the free energy change for the formation of one mole of the substance from the component elements in their standard states. These values are applicable at 25 °C and are found in thermodynamic tables. When propanol (CH3CH2CH2OH) is combusted, such as when in a gasoline blend, the following reaction occurs: 2CH3 CH2 CH2OH(1) + 902 (g)→6CO2(g)+8H2O(g) Based on the standard free energies of formation given in the table below, what is the standard free energy change for this reaction? The value of AG; for a substance gives a measure of the thermodynamic stability with respect to the component elements. Negative values for a formation reaction indicate thermodynamic stability of the product. In other words, the compound formed does not spontaneously decompose back into the component elements. Positive values for a formation reaction indicate thermodynamic instability of the product. Thus, the compound will spontaneously decompose, though the rate may be slow. AG Substance kJ/mol) СH3 CHCH2OН()| — 360.5 O2 (g) The sign of AG can be used to predict the feasibility of CO2 (8) -394.4 synthesizing a substance from its component elements. The standard free energy change for a reaction, AG°, is a state function and can be calculated from the standard free energies H2O(g) -228.6 of formation as follows: Express your answer to one decimal place and include the appropriate units.
