Consider these reactions, where M represents a generic metal.
- 2M(s)+6HCl(aq)⟶2MCl3(aq)+3H2(g) Δ?1=−651.0 kJ
- HCl(g)⟶HCl(aq) Δ?2=−74.8 kJ
- H2(g)+Cl2(g)⟶2HCl(g) Δ?3=−1845.0 kJ
- MCl3(s)⟶MCl3(aq) Δ?4=−210.0 kJ
Use the given information to determine the enthalpy of the reaction
2M(s)+3Cl2(g)⟶2MCl3(s)
