reaction 1 reversed: 2CO2+3H2O→C2H5OH+3O2?

Answered by maham237 @ 29/11/2020

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), than reversed reaction is endothermic (chemical reaction
that absorbs more energy than it releases) and has same value for enthalpy, but positive sign.
