Question

Consider these reactions, where M represents a generic metal.

1.  2M(s)+6HCl(aq)⟶2MCl3(aq)+3H2(g)   Δ?1=−693.0 kJ

2.  HCl(g)⟶HCl(aq)                                        Δ?2=−74.8 kJ

3.  H2(g)+Cl2(g)⟶2HCl(g)                            Δ?3=−1845.0 kJ

4.  MCl3(s)⟶MCl3(aq)                                  Δ?4=−149.0 kJ

 

Use the given information to determine the enthalpy of the reaction
