Question

Consider these reactions, where M represents a generic metal. 2M(s)+6HCl(aq)⟶2MCl3(aq)+3H2(g)ΔH1=−600.0 kJ HCl(g)⟶HCl(aq)  ΔH2=−74.8 kJ H2(g)+Cl2(g)⟶2HCl(g) ΔH3=−1845.0 kJ...

Consider these reactions, where M represents a generic metal.

  1. 2M(s)+6HCl(aq)⟶2MCl3(aq)+3H2(g)ΔH1=−600.0 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=−215.0 kJ

Use the given information to determine the enthalpy of the reaction

2M(s)+3Cl2(g)⟶2MCl3(s)

ΔH= kJ
