Consider the chemical equations shown here.

1. 2H₂ (g) + O₂ (g) ⇒ 2H₂O (g) | ΔH1 = -483.6 kJ/mol ΔH1 ÷ 2 = -241.8 kJ/mol

2. 3O₂ (g) ⇒ 2O₃ (g) | ΔH2 = 284.6 kJ/mol ΑH2 ÷ 2 = 142.3 kJ/mol
--------------------------------------------------------------------------------------------------------------

What is the overall enthalpy of reaction for the equation shown below?

3H₂ (g) + O₃ (g) ⇒ 3H₂O (g)

Consider the chemical equations shown here 1 2H g O g 2HO g ΔH1 4836 kJmol ΔH1 2 2418 kJmol 2 3O g 2O g ΔH2 2846 kJmol ΑH2 2 1423 kJmol What is the overall enth class=
