Calculate the standard enthalpy change for the reaction of the combustion of 1 mole of liquid ethanol (C2H5OH) at 298K and 1 atm. The balanced chemical equation for the reaction is: C2H5OH(l) + 3O2(g) → 2CO2(g) + 3H2O(l)Given:ΔHf°(C2H5OH(l)) = -277.7 kJ/molΔHf°(CO2(g)) = -393.5 kJ/molΔHf°(H2O(l)) = -285.8 kJ/molΔHf°(O2(g)) = 0 kJ/mol
