Consider these reactions, where M represents a generic metal. 2M(s)+6HCl(aq)2MCl 3 (aq)+3H 2 (g)H 1 =718.0 kJ HCl(g)HCl(aq) H 2 =74.8 kJ H 2 (g)+Cl 2...
Consider these reactions, where M represents a generic metal.
- 2M(s)+6HCl(aq)⟶2MCl 3 (aq)+3H 2 (g)ΔH 1 =−718.0 kJ
- HCl(g)⟶HCl(aq) ΔH 2 =−74.8 kJ
- H 2 (g)+Cl 2 (g)⟶2HCl(g) ΔH 3 =−1845.0 kJ
- MCl 3 (s)⟶MCl 3 (aq) ΔH 4 =−198.0 kJ
Use the given information to determine the enthalpy of the reaction
2M(s)+3Cl 2 (g)⟶2MCl 3 (s)
ΔH= ____kJ
