The standard enthalpies of formation, at 25.00 oC, of methanol (CH4O(l)), water (H2O(l)), and carbon dioxide (CO2(g)) are, respectively, -238.7 kJ/mol, -285.8 kJ/mol, and -393.5 kJ/mol. Calculate the change in the entropy of the surroundings (in J/K) upon the combustion of 14.3 g of methanol under a constant pressure of 1.000 atm and a temperature of 25.00 oC. N. B. Combustion is the reaction of this substance with molecular oxygen to produce water and carbon dioxide.
