Problem Details

Consider these reactions, where M represents a generic metal

1. 2M(s) + 6HCl(aq) → 2MCl3(aq) + 3H2(g) ΔH= -749.0 KJ

2. HCl(g) → HCl(aq) ΔH2 = -74.8 KJ

3. H2(g)+Cl2(g) → 2HCl(g) ΔH= -1845.0 KJ

4. MCl3(s) → MCl3(aq) ΔH= -298.0 KJ

Use the information above to determine the enthalpy of the following reaction.

2M(s) + 3Cl2(g) → 2MCl3(s) ΔH =
