Mandatory upload of work for this problem. All uploaded work must show the problem number, must be in the correct orientation and easily legible, and must have good contrast and no shadows. Using the standard free energies of formation found in Appendix C (you may not use values from any other source), calculate AGº in kJ for the combustion of liquid butane in which all products are cooled to 25°C. Be sure to consider the physical states of all reactants and products. Use only one decimal place in your answer. 2 C4H10 (1) + 13 O2 (g) – 8 CO2 (g) + 10 H20 (1) AGº = KJ
