Given the following equations and their respective enthalpy changes:1) 2H2 (g) + O2 (g) → 2H2O (l) ΔH = -484 kJ/mol 2) C2H5OH (l) + 3O2 (g) → 2CO2 (g) + 3H2O (l) ΔH = -1,367 kJ/mol 3) C2H5OH (l) → C2H4 (g) + H2O (g) ΔH = +44 kJ/mol Using Hess’s Law, determine the ΔH for the following reaction: C2H5OH (l) → 2CO2 (g) + 3H2 (g)
