The standard enthalpies of formation, at 25.00°C, of methanol (CH4O(l)), water (H2O(l)), and carbon dioxide (CO2(g)) are -238.7 kJ/mol, -285.8 kJ/mol, and -393.5 kJ/mol respectively. What is the change in surrounding entropy (in J/K) when burning 12.1 g of methanol under a constant pressure of 1,000 atm at 25.00° (N.B., combustion is the reaction of a substance with molecular oxygen to produce water and carbon dioxide)?
