What is the enthalpy for reaction 1 reversed? reaction 1 reversed: 2co2+3h2o→c2h5oh+3o2?

THIS IS THE BEST ANSWER 👇

The answer is: the enthalpy for reaction 1 of reverse is 1370 kJ / mol.

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