Methanol \(\left(\mathrm{CH}_{3} \mathrm{OH}\right)\) burns in oxygen to form carbon dioxide and water. Write a balanced equation for the combustion of liquid methanol and calculate \(\Delta H_{\mathrm{rxn}}^{\circ}, \Delta S_{\mathrm{rxn}}^{\circ}\), and \(\Delta G_{\mathrm{rxn}}^{\circ}\) at \(25^{\circ} \mathrm{C}\). Is the combustion of methanol spontaneous?
