The answer is: the enthalpy for reaction 1 reversed is 1370 kJ/mol.Balanced chemical reaction 1: C₂H₅OH + 3O₂ → 2CO₂ + 3H₂O ΔrH= -1370 kJ/mol.Reaction 1 is exothermic reaction (heat is released), which reverses the reaction is endothermic (a chemical reaction that absorbs more energy than it releases) and has the same value for the enthalpy, but of positive sign.
