Consider these reactions, where M represents a generic metal.
1. 2M(s) + 6HCl(aq) → 2MCl3(aq) + 3H2(g) ΔH1 = -881.0 kJ
2. HCl(g) → HCl(aq) ΔH2 = -74.8 kJ
3. H2(g) + Cl2(g) → 2HCl(g) ΔH3 = -1845.0 kJ
4. MCl3(s) → MCl3(aq) ΔH4 = -316.0 kJ
Use the information above to determine the enthalpy of the following reaction
2M(s) + 3Cl2(g) → 2MCl3(s) ΔH = __________ kJ
The question belongs to Chemical Engineering and it discusses about calculation of enthalpy for the reactions given in the question.
