Aluminum chloride can be formed from its elements:
(i) 2Al(s)+3Cl2(g)⟶2AlCl3(s) ΔH°= ?
Use the reactions here to determine the ΔH° for reaction (i):
(ii) HCl(g)⟶HCl(aq) ΔH∘(ii)=−74.8kJ
(iii) H2(g)+Cl2(g)⟶2HCl(g) ΔH∘(iii)=−185kJ
(iv) AlCl3(aq)⟶AlCl3(s) ΔH∘(iv)=+323kJ
(v) 2Al(s)+6HCl(aq)⟶2AlCl3(aq)+3H2(g) ΔH∘(v)=−1049kJ
