Calculating Enthalpy of formation problem. Please help!?

How do I do this problem? Calculate the reaction enthalpy of formation of anhydrous aluminum chloride, 2 Al(s) + 3 Cl2(g) à 2 AlCl3(s) from the following data: 2 Al(s) + 6HCl(aq) à 2 AlCl3(aq) + 3 H2(g) ΔHorx = -1049 kJ HCl(g) à HCl(aq) ... show more How do I do this problem?


Calculate the reaction enthalpy of formation of anhydrous aluminum chloride,
2 Al(s) + 3 Cl2(g) à 2 AlCl3(s) from the following data:

2 Al(s) + 6HCl(aq) à 2 AlCl3(aq) + 3 H2(g) ΔHorx = -1049 kJ

HCl(g) à HCl(aq) ΔHorx = -74.8 kJ

H2(g) + Cl2(g) à 2 HCl(g) ΔHorx = -185 kJ

AlCl3(s) à AlCl3(aq) ΔHorx = -323 kJ

Would you expect the equilibrium constant to rise or fall with increasing temperature for this reaction?
