In this problem, we are asked to determine the enthalpy of the following reaction
2 M(s) + 3 Cl2(g) → 2 MCl3(s)
Consider these reactions, where M represents a generic metal.
Consider these reactions, where M represents a generic metal.
1. 2 M(s) + 6 HCl(aq) → 2 MCl3(aq) + 3 H2(g) ΔH1 = -623.0 kJ
2. HCl(g) → HCl(aq) ΔH2 = -74.8 kJ
3. H2(g) + Cl2(g) → 2 HCl(g) ΔH3 = -1845.0 kJ
4. MCl3(s) → MCl3(aq) ΔH4 = -309.0 kJ
Use the information above to determine the enthalpy of the following reaction
2M(s) + 3Cl2(g) → 2MCl3(s) ΔH = kJ
