Calculate $\Delta$ G ^$\circ$ for the Combustion of Ethanol Vapor, C₂H₅OH(g), at 750

Calculate $\Delta$ G ^$\circ$ for the combustion of ethanol vapor, C₂H₅OH(g) , at 750 ^$\circ$ C in oxygen to form carbon dioxide and water vapor. The following data is valid at 25 ^$\circ$ C: $\begin{array}{lcc}&\Delta \mathrm{H}_{\mathrm{f}}^{\circ}(\mathrm{kJ} / \mathrm{mol}) & \Delta \mathrm{G}_{\mathrm{f}}^{\circ}(\mathrm{kJ} / \mathrm{mol}) \\\hline\mathrm{C}_{2} \mathrm{H}_{5} \mathrm{OH}(\mathrm{~g}) & -234.8 & -167.9 \\\mathrm{O}_{2}(\mathrm{g}) & 0 & 0 \\\mathrm{H}_{2} \mathrm{O}(\mathrm{g}) & -241.8 & -228.6 \\\mathrm{CO}_{2}(\mathrm{g}) & -393.5 & -394.4\end{array}$

A) -1407 kJ/mol
B) -2151 kJ/mol
C) -1307 kJ/mol
D) -4486 kJ/mol
E) -1377 kJ/mol
