This application will calculate the Gibbs Free Energy of Formation of ethanol (C2H5OH) at any temperature, employing thermodynamic data from the ThermophysicalData[Chemicals] package.

The results (at various temperatures) are compared with data from the CRC Handbook of Chemistry and Physics. Good agreement is found.

This chemical reaction describes how ethanol is formed from carbon, hydrogen and oxygen (in their stable states).

2 C (gr) + 3 H2 (g) + 0.5 O2 (g) ? C2H5OH (g)

Literature values of the Gibbs free energy of formation are normally only tabulated at standard temperature, or for a small number of temperatures. However, the ThermophysicalData:-Chemicals package contains temperature-dependent curve fits of enthalpy and entropy over a wide range of temperatures; these empirical relationships can be interrogated at any temperature.

This means that Maple will help you calculate the Gibbs free energy of formation of ethanol at any temperature (assuming that the enthalpy and entropy are within the bounds of the fitted data).
