2. Consider the reaction CH3OH(g) +HO2(g) CO2(g) 2H,0g) â + Calculate the AH for the above reaction. The standard enthalpies of formation for CHOHg), cotg), and H2O(g) are-201.0 kVmiol,-993.5 kJ/mol, and-241.8 kJ/mol, respectively a. b. would Î1P for the reaction be different if liquid (instead of gaseous) water were formed? c. Calculate the heat evolved when 50.0 g of methanol reacts with excess oxygen. d. If the heat evolved in a is used to heat up a sample of an unknown liquid from 25.0 C to 91.2 0 , calculate the mass of this sample, assuming the molar specific heat of the liquid is 61.2 J/mol-K with molar mass 31.8 g/mol (and no heat lost to surroundings). e. If the heat evolved in a were used to warm an Fe sample (0449 V/gk) of equal mass (to the liquid in d, explain whether the temperature change of the iron is higher or lower than that of the liquid? No calculation is necessary
